Sandeep connected one end of bulb to battery's positive terminal with copper wire and negative terminal with plastic wire. But bulb is not glowing. What could be the reason behind this?
Answers
Answer:
Explanation:
plastic wire is non conductor of electricity so current is not passing through it.
According to the Question :
Sandeep connected one end of bulb to battery's positive terminal with copper wire and negative terminal with plastic wire. But bulb is not glowing .
We have learnt that plastic is a bad conductor also called as an insulator which doesn't let electricity to pass through it . And we learnt that electricity must pass through positive to negative terminal in order to get the light bulb lit . But when negative terminal is an insulator ; of course the bulb will not glow .
One thing to note is that plastic doesn't have free ions which will conduct electricity and let it pass through . Thus , an insulator .
Hence the bulb doesn't glow.
