Chapter 35, Problem 7A

If one of three lamps blows out when connected in parallel, what happens to the current in the other two?

To determine

The effect of blow out of one lamp from the three lamps in a parallel circuit.

Explanation of Solution

Introduction:

The electric devices in parallel circuit are not connected by end to end connection. The removal of one device from the parallel circuit does not affect the flow of supply in the circuit.

The voltage for each device in the parallel circuit remains same and each device acts independently. The interruption in the supply of one device does not affects the supply the other devices in the parallel circuit.

Conclusion:

The blow out of one lamp from three lamps in the parallel circuit does not affect the current in other two lamps.
