Question

A copper wire has a resistance of 10 ohm. It is streched by one-tenth of its original lenght. Then its resotance will be

Answer 1

hii mate

we know that length,if increased current flowing decrease that is resistance increase.

x=10 ohm

1/10x=y

y=10*1/10

y=1 ohm

hence 1 ohm of resistance increased in 10

hence answer is 11 ohm
