Question

Ten bulbs are connected in a series circuit to a power supply line. Ten identical bulbs are connected in a parallel circuit to an identical power supply line.

1. Which circuit would have the highest voltage across each bulb?
2. In which circuit would the bulbs be brighter?
3. In which circuit, if one bulb blows out, all others will stop glowing?
4. Which circuit would have less current in it?

Answer 1

1. The parallel circuit will have the highest voltage across each bulb.
2. In a parallel circuit, each bulb has the highest voltage.
3. The appliance can be controlled individually using an individual switch when a parallel circuit is used.
4. The working of the appliances is not dependent on each other when they are connected in parallel.
