Inductors

Q1: The voltage across a coil when di/dt = 20 mA/s and L = 8 H is

A 16 mV

B 160 mV

C 1.6 mV

D 2.5 mV

ANS:B - 160 mV

We all know that the formula of the inductor for finding voltage. Is Ldi/it.
So data given,
L = 8*10^-6 H.

di/DT=20*10^-3/10^-6.
So according to formula.
V = 8 * 10^-6 * 20 * 10^-3/10^-6.
= 160*10^-3v.
