Question

Using the circuit given below, state which of the following statement is correct?

(a) When S₁ and S₂ are closed, lamps A and B are lit.
(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.

Open in App

Solution

(c) With S₂open and S₁ closed, A and B are lit.
This is so because if the switch, S₂ is open, the current will flow through lamp A because it is a parallel circuit.
