To solve this, we need to look at how the electricity flows in each circuit.
Key Rule:
*
Series Circuit: The components (like light bulbs) are arranged in a single line, one after another. There is only
one path for the electricity to flow. If you trace the wire from the battery, it goes through every bulb before returning to the battery.
*
Parallel Circuit: The components are arranged on separate branches. The electricity has
more than one path to choose from. The wires split apart to go to different bulbs and then join back together.
Let's look at each number:
1.
Circuit 1: Look at the wires coming from the switch. The wire splits into two separate paths. One path goes to the top bulb, and the other path goes to the bottom bulb. Because there are two separate paths, this is a
Parallel circuit.
2.
Circuit 2: Trace the wire from the battery. It goes through the switch, then through the first bulb, then directly into the second bulb, and finally back to the battery. There is only one single loop. This is a
Series circuit.
3.
Circuit 3: Similar to number 2, trace the path. Battery -> Bulb -> Switch -> Bulb -> Battery. It is one single continuous line. This is a
Series circuit.
4.
Circuit 4: Look at the wiring around the bulbs. The current comes from the battery and splits. One part goes to the top bulb, and another part goes down to the bottom bulb and switch. They are on separate branches. This is a
Parallel circuit.
5.
Circuit 5: Trace the long winding wire. It goes from the battery, through the switch, through the first bulb, then the second, then the third, and back home. It never splits. It is one single path. This is a
Series circuit.
6.
Circuit 6: Look at the connection between the two bulbs. The wire comes from the switch and splits into two directions—one for the top bulb and one for the bottom bulb. Since the path divides, this is a
Parallel circuit.
Final Answer:
1. Parallel circuit
2. Series circuit
3. Series circuit
4. Parallel circuit
5. Series circuit
6. Parallel circuit
