ln an electric circuit, a battery and a bulb have been connected and the battery consist of two cell 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?
Answers
There can be 2 reasons for the above situation :
1) The cells used may got low potential due to excess use therefore we may check the voltage of each cell by voltmeter.
2) The bulb used must have some problem like it may have been fused which makes it not glowing.
Hope it helps #))
Answer:
Explanation:
We need to perform the following test to detect the reason why the bulb is not glowing:
1. First, we need to check how the battery terminals are connected to each other. It should be ensured that the positive terminal of a battery is connected to the negative terminal of another battery. If all the batteries are linked or connected in this fashion and even then the bulb is not glowing, then we need to check an alternate option.
2. Secondly, we need to check if there are any broken wires in the circuit. By ensuring that the wires that are used for linking or connecting the different electrical components are not broken in between it helps in detecting that the circuit is closed. Further, this also helps to ensure that the wires are not broken somewhere in between because of which the bulb is not glowing. If this doesn’t work, we need to move to the next test.
3. Finally, we need to check how the connecting wires are plugged into the bulb. This will ensure that the bulb is properly connected to the batteries as shown in the diagram below. Even then, if the bulb does not glow, then we need to replace the batteries of the bulb with a new set.
