To solve the problem, we need to match each electric circuit diagram with its corresponding schematic diagram. Let's analyze each row step by step:

Row 1:

- Electric Circuit: The circuit shows two batteries connected in series and a single light bulb.
- Schematic Diagram: We need to represent this using standard symbols:
- Batteries: Represented by two parallel lines of different lengths (longer line for positive, shorter for negative).
- Light Bulb: Represented by a zigzag line.
- Wires: Represented by straight lines connecting components.

Schematic Diagram:
```
+---| |---+---[zigzag]---+
| | |
+-----------------+
```

Row 2:

- Electric Circuit: The circuit shows three batteries connected in parallel and two light bulbs also connected in parallel.
- Schematic Diagram: We need to represent this using standard symbols:
- Batteries: Three sets of parallel lines (one for each battery).
- Light Bulbs: Two zigzag lines.
- Wires: Straight lines connecting components in parallel.

Schematic Diagram:
```
+---| |---+ +---| |---+ +---| |---+
| | | | | | | |
+---------+---------+---------+
| |
[zigzag] [zigzag]
| |
+----------------+
```

Row 3:

- Electric Circuit: The circuit shows two light bulbs connected in series with a switch.
- Schematic Diagram: We need to represent this using standard symbols:
- Light Bulbs: Two zigzag lines.
- Switch: Represented by a break in the wire with a gap.
- Wires: Straight lines connecting components in series.

Schematic Diagram:
```
+---[zigzag]---[switch]---[zigzag]---+
```

Row 4:

- Electric Circuit: The circuit shows four light bulbs connected in a complex arrangement, likely involving both series and parallel connections.
- Schematic Diagram: We need to represent this using standard symbols:
- Light Bulbs: Four zigzag lines.
- Wires: Straight lines connecting components in series and parallel.

From the given schematic diagram in Row 4, it appears that the light bulbs are arranged in a combination of series and parallel. The exact configuration depends on how the wires are connected, but the provided schematic already matches this description.

Final Answer:

Here is the completed table with the matching schematic diagrams:

1. Row 1:
- Electric Circuit: Two batteries in series and one light bulb.
- Schematic Diagram:
```
+---| |---+---[zigzag]---+
| | |
+-----------------+
```

2. Row 2:
- Electric Circuit: Three batteries in parallel and two light bulbs in parallel.
- Schematic Diagram:
```
+---| |---+ +---| |---+ +---| |---+
| | | | | | | |
+---------+---------+---------+
| |
[zigzag] [zigzag]

+----------------+
```

3. Row 3:
- Electric Circuit: Two light bulbs in series with a switch.
- Schematic Diagram:
```
+---[zigzag]---[switch]---[zigzag]---+
```

4. Row 4:
- Electric Circuit: Four light bulbs in a complex series-parallel arrangement.
- Schematic Diagram (already provided):
```
+---[zigzag]---[zigzag]---+

+---[zigzag]---[zigzag]---+
```

Thus, the final answer is:
