Question

3. 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

Answer:

This would be a troubleshooting flow in order from the easiest and most obvious check to ones requiring test gear.

Visually check to make sure the batteries are connected properly; in series and not opposition. Series would be -+-+ so the voltage is additive. With a ++ or - - connection, resultant voltage will be zero.

Using a voltmeter, check voltage at bulb connection or socket. This will determine if power is available to the bulb.

If steps 1 & 2 are good, remove the bulb and check for resistance using an ohmmeter. Open or extremely high resistance indicates either an open bulb or a failure.
