Ten bulbs are connected in a series circuit to a power supply line. Ten identical bulbs are connected in a: a) an identical power supply line b) which circuit would have the highest voltage across each bulb? c) in which circuit would the bulbs be brighter? d) in which circuit, if one bulb blows out, all others will stop glowing? which circuit would have less current in it?

Answer
- To have an identical power supply line, the circuit must be parallel
- When the circuit is parallel, each bulb will have highest voltage
- The working of the appliance can be controlled using individual switch when a parallel circuit is used
- The working of the appliances are not dependent on each other when they are connected in parallel
