Three identical lamps are connected in parallel with a battery. The total current in the circuit is 12A.What will be the total current if one of the lamp fuses?
Answers
there will be no effect on the current flowing through the circuit ie.the current will be same in the circuit because in a parallel connection if one appliance fails to work it doesn't affects other two appliance and the current drawn will be same in both of the remaining bulabs however, the current which was being drawn by the fused bulb will not be utilised.
hope it helps...
Answer:
Components connected in parallel are connected so the same voltage is applied to each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.
In this case, 3 identical bulbs are connected in parallel. Therefore, the voltage remains the same across each bulb but the current is equally shared by all the three bulbs, that is, each bulb needs 2 A of current out of total 6 A as given in the question.
When one bulb, is fused out, only bulbs burn and only 4 A current is used.
Hence, the total current drawn from the battery when one bulb fuses is 4 A.
