If number of turns in a coil is increased from 10 to 100, its inductance becomes .... times the original value.

A

10

B

100

C

`1/10`

D

25

Text Solution

Verified by Experts

The correct Answer is:
B
`L prop N^2`
`therefore L_2/L_1=(N_2/N_1)^2`
`=(100/10)^2`
`therefore L_2/L_1=100 " " therefore L_2=100 L_1`
