Question

In an electric circuit, a battery and a bulb have been connected and the battery consists of two cells of equal potential difference. if the bulb is not glowing ,then which tests will you perform in order to find out the reason for the bulb not glowing ?

Answer 1

The current flow is actually electrons flow from the part of the V terminal to the +ve terminal via the outside wire.

Next bulb B will glow, if the voltage drop where I is the current as well as R2 the resistance of bulb B.

finally the bulb a will glow voltage drop 1 R3 where I is the current and R3. Here the sequence of the light is First C, B and last A

Answer 2
