31.
The voltage of the source in circuit shown __________ if i(t) = - 20e-2t is
Answer: Option
Explanation:
Voltage across capacitor = i(t) x 1 
- 20 e-2t
Current across capacitor = 
120 e-2t
Source current Is = iC (t) + iR(t)
120 e-2t - 20e-2t 100 e-2t
VR = 100 e-2t
33.33 e-2t, Vs = 100 e-2t - 20 e-2t - 33.33 e-2t
Vs = 46.6 e-2t volt.
