Consider a current source i(t) connected across a 0.5 mH inductor, where i(t) = 0 A for t < 0 and i(t) = (8e-250t - 4e-1000t) A for t ≥ 0. The voltage across the inductor at t = 0 s is
  • a)
    0.5 V
  • b)
    1 V
  • c)
    2 V
  • d)
    4 V

Concept:
When current source i(t) connected across an inductor(L), then the voltage across the inductor is given as
When voltage source v(t) connected across a capacitor(C), then the current across the capacitor is given as
Calculation:
Given i(t) = (8e-250t - 4e-1000t) A for t ≥ 0, L = 0.5 mH
Then the voltage across the inductor is given as
At t = 0 its value is given as
VL = 0.5 × 10-3 × (- 2000 + 4000)
VL = 1 V
