:. 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?
Answers
Answer:
The tests to perfrom if the bulb is not glowing are:
Step-by-step explanation:
1. Check the connection of wires. Is any wire connected wrongly or in the wrong terminal of the batter?
2. Check the battery. Is it drained and already used?
3. Check the bulb. Is the tungsten of the bulb broken? If yes, then the bulb will not work under any circumstances.
Answer:
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.
