An e.m.f. of `12"volts"` is produced in a coil when the current in it changes at the rate of `45 amp//minute`. The inductance of the coil is

A

`0.25` henry

B

`1.5` henry

C

`9.6` henry

D

`16.0`henry

Text Solution

Verified by Experts

The correct Answer is:
D
`e=L(di)/(dt)implies12=Lxx(45)/(60)impliesL=16H`
