ElectroMagnetic InductionHard
Question
In the inductive circuit given in fig. the current rises after the switch is closed. At instant, when the current is 15 mA. Then potential difference across the inductor is : -
Options
A.40 V
B.80 V
C.160 V
D.0
Solution
100 = VR + VL But VR = (4000) (15 × 10-3) = 60 volt
⇒ VL = 40 volt
⇒ VL = 40 volt
