PhysicsEasysingle choice
A current of 2A is increasing at a rate of 4 A/s through a coil of inductance 2 H. The energy stored in the inductor per unit time in given instant is
Options:
Answer:
C
Solution:
Potential difference across coil is
or V = (2) (4) = 8V
Now energy stored per unit time
= power = Vi
= (8) (2) = 16 J/s
