Question

As shown in the figure, Radhika joins two bulbs with an electric cell. She observes that

the filament of the bulb B is broken. Will the bulb A glow in this circuit? State the

reason. ​

Answer 1

Answer:

The bulb may not glow because of the following reasons:

1. Liquid in the beaker may be non-conducting. In such a case,

2. The conduc tivity of the liqu id may be very low and so the current flowing through the circuit may be too weak to produce enough heat in the fila ment of the bulb so as to make it glow..
