Ten bulbs are connected in a series circuit to a power supply line and

1.	Ten bulbs are connected in a series circuit to a power supply line and ten identical bulbs are connected in a parallel circuit to an identical power supply line. (a) Which circuit would have the highest voltage across each bulb? (b) In which circuit would the bulb be brighter? (c) If one bulb blows out, in which circuit will other bulb stop glowing?
Answer» (a) Voltage is dependent on I and R. Hence, in parallel circuit. (b) In parallel connection (c) In series connection
