Gourang made an electric circuit with three bulbs B_(1), B_(2) and B_(3) a cell and two switches S_(1) and S_(2) as shown in figure. He notes his observation when (a) S_(1) is closed and S_(2) is open, (b) S_(2) is closed and S_(1) is open. He also found that a bulb whose failure made the circuit 'open' irrespective of the status of S_(1) and S_(2) . What are his observation.
