Let's analyze each of the four circuits shown in the worksheet to determine whether they are
series or
parallel circuits.
---
🔍 Key Concepts:
-
Series Circuit: Components are connected
end-to-end, forming a
single path for current. The same current flows through all components.
-
Parallel Circuit: Components are connected across common points, providing
multiple paths for current. The voltage across each component is the same.

✔ Circuit 1:
- There is
one battery and
one bulb.
- The wire forms a
single loop from the battery to the bulb and back.
- Only
one path for current.
➡️ This is a
SERIES circuit.
>
✔ Answer: SERIES
---
✔ Circuit 2:
- One battery and
two bulbs.
- The bulbs are connected
one after the other in a single loop.
- Current must go through the first bulb, then the second, before returning to the battery.
- Only
one path for current.
➡️ This is a
SERIES circuit.
>
✔ Answer: SERIES
---
✔ Circuit 3:
- One battery and
three bulbs.
- The bulbs are arranged such that
each bulb has its own separate path from the battery (positive terminal to negative).
- The wires split into three branches, each going to a bulb, then recombine.
- Each bulb receives the full voltage (2V), and if one fails, others stay lit.
➡️ This is a
PARALLEL circuit.
>
✔ Answer: PARALLEL
---
✔ Circuit 4:
- One battery and
three bulbs.
- The bulbs are connected
in a single continuous loop — the current goes through one bulb, then another, then the third, and returns to the battery.
- There’s
only one path for current.
- Even though the wires curve, there is
no branching.
➡️ This is a
SERIES circuit.

💡 Explanation Recap:
-
Series: One path, components in line.
-
Parallel: Multiple paths, components on separate branches.
You can identify parallel circuits by looking for
branches or
splitting wires leading to different components.
