Electric circuits miscellaneous

  1. A current shown in the figure passes through a pure inductance at 3 mH. The instantaneous power in watts during 0 < t < 2 ms is

    1. 25000 t
    2. 5000 t
    3. 75000 t
    4. 100000 t
Correct Option: C

Instantaneous power, p = vi
For the interval 0 < t < 2,

i =
10
× 103 t (tns)
2

v = L
di
= 3 × 10-3 ×
10
× 103
dt2

∴ p = 75,000 t
