Electric Circuits Worksheets | Types, Ohms Law, Hazards, Safety - Free Printable

Let's solve this step-by-step. The worksheet asks you to match electric circuits (on the left) with their corresponding schematic diagrams (on the right), using proper electrical symbols.

We are given a table with two columns:

- Left column: Electric Circuit (visual representation)
- Right column: Schematic Diagram (to be completed)

There are four rows, each showing a circuit on the left and a blank space for the schematic on the right (or vice versa). Some rows have the circuit, others have the schematic — we need to complete the missing side.

Step 1: Understand Standard Electrical Symbols

Before solving, recall common symbols:

- Battery = `| |` or `+ -` (long line = positive, short = negative)
- Light Bulb = Circle with an "X" inside
- Switch = A break in the wire with a line that can connect (open or closed)
- Resistor / Cell = Rectangle or zigzag (but here, batteries are shown as cells)
- Wires = Straight lines
- Parallel = Components on separate branches
- Series = Components connected end-to-end

---

Now let’s go row by row.

---

🔹 Row 1:

#### Left: Electric Circuit
- Two green batteries (cells) in parallel
- One light bulb
- All connected together

So:
- Two batteries connected side-by-side (parallel)
- Light bulb in series with them?

Wait: Looking closely — both batteries are connected across the same points, so they are in parallel.
The bulb is connected across the same points too → so the bulb is also in parallel with the battery combination.

But actually, since it's a single loop? Wait — no: the diagram shows two batteries side-by-side, then one bulb.

Actually, it looks like:
- Two batteries in parallel
- Connected to one bulb → so the entire circuit has parallel batteries powering a single bulb

So the schematic should show:
- Two batteries in parallel (both positive and negative ends connected together)
- One bulb in the circuit
- No switch shown

But there is no switch in this circuit.

✔ So the schematic should be:
- Two batteries (cells) in parallel
- One bulb in series with the combination

But wait: if the batteries are in parallel, and the bulb is connected across them, then the bulb is in parallel with the battery pair.

But in simple circuits, batteries in parallel provide more current but same voltage.

So the correct schematic would be:
- Two batteries in parallel
- One bulb connected across the same terminals

That means:
- The bulb is in parallel with the battery pair.

But since the bulb is the only load, the full circuit is:
- Parallel batteries → connected to a single bulb

So the schematic:
```
+----[Battery]----+
| |
+----[Battery]----+
|
[Bulb]
|
===
```

But standard way: draw two batteries in parallel, then a bulb in series? No — not unless it's in series.

Wait: if the bulb is connected across the battery terminals, it's in parallel.

But in most cases, the bulb is in series with the power source.

Looking again at the image:

It shows:
- Two batteries side-by-side (parallel)
- Then a bulb connected to the output

So the flow is: from battery (+) → bulb → battery (-)

But both batteries are connected to the same wires → so they are in parallel, and the bulb is in series with the combined battery source.

Yes! That makes sense.

So:
- Two batteries in parallel
- One bulb in series with them

✔ So the schematic should show:
- Two batteries in parallel (positive ends together, negative ends together)
- A wire from the positive junction → bulb → negative junction

So:

```
+--------[Bulb]--------+
| |
[Battery] [Battery]
| |
+----------------------+
```

But batteries are drawn as `| |`, so:

```
+------------------+
| |
[ | ] [ | ]
| |
+-----[Bulb]-------+
```

But we don’t need to draw it here — just describe.

So Row 1 Schematic:
- Two batteries in parallel
- One bulb in series with the combination
- No switch

✔️ So draw: two batteries side-by-side (parallel), then a bulb in the main path.

---

🔹 Row 2:

#### Left: Electric Circuit
- Three green batteries stacked vertically → in series
- Three bulbs, each in a separate branch → so three parallel bulbs
- The three bulbs are connected across the battery pack

So:
- Battery: 3 in series
- Load: 3 bulbs in parallel

So the schematic should show:
- Three batteries in series (end-to-end)
- Three bulbs in parallel (each on its own branch)
- All connected in a loop

So:

```
+---------[Bulb1]----------+
| |
+---------[Bulb2]----------+
| |
+---------[Bulb3]----------+
| |
[ | ][ | ][ | ] |
| |
+--------------------------+
```

But better:

- Draw a battery chain: `| | |` (three in series)
- Then three branches with bulbs in parallel
- Switch? Not shown → no switch

So schematic:
- Series batteries
- Parallel bulbs

✔ So Row 2 Schematic:
- Three batteries in series
- Three bulbs in parallel
- No switch

---

🔹 Row 3:

#### Right: Schematic Diagram Given
- Two bulbs in series
- One battery
- One switch

So the electric circuit must show:
- A battery
- A switch
- Two bulbs connected one after another (series)
- Wires connecting all

So the visual circuit should have:
- One battery
- One switch (maybe open or closed)
- Two bulbs in a line
- All connected in a single loop

So draw:
- A battery
- A switch (shown as open or closed — probably open)
- Two bulbs in a straight line
- Wires connecting them

✔ So Row 3 Electric Circuit:
- One battery
- One switch
- Two bulbs in series

---

🔹 Row 4:

#### Right: Schematic Diagram Given
- Three bulbs in parallel
- One battery
- One switch
- But the switch is in the main line, before the split

So:
- Battery → switch → then splits into three branches, each with a bulb
- So bulbs are in parallel
- Switch controls all bulbs

So the electric circuit must show:
- One battery
- One switch
- Three bulbs, each on its own branch
- All connected to the same power source

So draw:
- A battery
- A switch in the main wire
- Three bulbs in separate branches, all connected between the same two points

This matches the description.

✔ So Row 4 Electric Circuit:
- One battery
- One switch
- Three bulbs in parallel

---

Final Matching:

Let’s now match each row:

| Row | Electric Circuit | Schematic Diagram |
|-----|------------------|-------------------|
| 1 | Two batteries in parallel, one bulb in series | ✔ Draw: two batteries in parallel, one bulb in series |
| 2 | Three batteries in series, three bulbs in parallel | ✔ Draw: three batteries in series, three bulbs in parallel |
| 3 | ??? | Given: two bulbs in series, battery, switch → draw that circuit |
| 4 | ??? | Given: three bulbs in parallel, battery, switch → draw that circuit |

But the arrows suggest matching.

Look at the arrows:

- From Row 1 → Row 2: lightning bolt → maybe indicates connection?
- But actually, the arrows are decorative.

Wait — look at the shapes around the boxes:

- Each box has a shape: circle, square, diamond, etc.
- These may indicate which row connects to which.

But more likely, the task is to complete the missing half of each row.

So:

- Rows 1 and 2: have circuit on left → need schematic on right
- Rows 3 and 4: have schematic on right → need circuit on left

Yes!

So:

✔ Row 1: Complete Schematic Diagram

- Two batteries in parallel
- One bulb in series
- No switch

Schematic:
```
+-----------+
| |
[ | ] [ | ]
| |
+----[Bulb]--+
```

But properly:
- Draw two batteries side by side, positive ends connected, negative ends connected
- Wire from positive junction → bulb → negative junction

Standard symbol:
- Battery: `| |` (long = +, short = -)
- So two batteries in parallel: `| |` and `| |` with top ends joined, bottom ends joined
- Then wire from top → bulb → bottom

So:

```
+-------------------+
| |
[ | ] [ | ]
| |
+----[Bulb]---------+
```

But we don't need to draw — just explain.

✔ So fill in the blank with:
- Two batteries in parallel
- One bulb in series
- No switch

---

✔ Row 2: Complete Schematic Diagram

- Three batteries in series
- Three bulbs in parallel

Schematic:
- Draw three batteries in series: `| | |` (connected end-to-end)
- Then three branches with bulbs in parallel
- Connect all to form a loop

```
+-------------------+
| |
| [Bulb1] |
| |
| [Bulb2] |
| |
| [Bulb3] |
| |
[ | ][ | ][ | ] |
| |
+-------------------+
```

But better:

```
+--------------------+
| |
| [Bulb1] |
| |
| [Bulb2] |
| |
| [Bulb3] |
| |
+--------+-----------+
|
[Battery1][Battery2][Battery3]
|
+------------+
```

Yes.

✔ Row 3: Complete Electric Circuit

Given schematic: two bulbs in series, battery, switch

So draw:
- A battery
- A switch (drawn as open)
- Two bulbs in a line
- Wires connecting them

Example:

```
+-------------------+
| |
[Battery] |
| |
| [Bulb1]|
| |
| [Bulb2]|
| |
| [Switch]|
| |
+-------------------+
```

But better: a simple loop:

```
[Battery] --- [Switch] --- [Bulb1] --- [Bulb2] --- back to battery
```

So in visual:
- Battery
- Switch (open)
- Two bulbs in a row
- All connected with wires

---

✔ Row 4: Complete Electric Circuit

Given schematic: three bulbs in parallel, battery, switch in main line

So draw:
- Battery
- Switch
- Then three separate paths, each with a bulb
- All connected to same points

Visual:
- Battery
- Switch
- Then three wires going out, each with a bulb, then back to battery

Like a "Y" shape with three arms.

✔ Final Answer Summary:

| Row | Electric Circuit | Schematic Diagram |
|-----|------------------|-------------------|
| 1 | Two batteries in parallel, one bulb in series | Draw: two batteries in parallel, one bulb in series |
| 2 | Three batteries in series, three bulbs in parallel | Draw: three batteries in series, three bulbs in parallel |
| 3 | One battery, one switch, two bulbs in series | Draw: battery → switch → bulb → bulb → back |
| 4 | One battery, one switch, three bulbs in parallel | Draw: battery → switch → three parallel branches, each with a bulb |
