Using the circuit given below, state which of the following statement is correct?
img...........................
  • A
    When S1 and S2 are closed, lamps A and B are lit.22
  • B
    With S1 open and S2 closed, A is lit and B is not lit.
  • C
    With S2 open and S1 closed A and B are lit.
  • D
    With S1 closed and S2 open, lamp A remains lit even if lamp B gets fused.
✓

Answer

  1. With S2 open and S1 closed A and B are lit.

Explanation:

This is so because if the switch, S2 is open, the current will flow through lamp A because it is a parallel circuit.
