The inductance is 120mH
The current is 150mA/s

|The inductance is 120 mH = 120*10^-3H.
The current is 150 mA/sec =150*10^-3A/sec.
V = L(di/dt).

|Both are right.|

The answer should be 0.018v, not 0.0018v.

|@Suryankya : your answer is right because we take all quantity in same before solving the problem.|
|Gangadhar said: (Dec 21, 2018)|
|V = L * (di/dt) = (120 * 150)m * m =18000 m * m =18mv.|
