PHYS345 Electricity and Electronics

Answer for D7-12

For t <3 s:
vC = (5 V) exp(-t/2 s) + 5 V

For t >3 s:
vC = (6.12 V) exp(-[t-3 s]/4 s)

Transient voltage across capacitor

Answer for D7-6

For t <3 s:
iL = (2 A) exp(-t/2 s)
VL = (-2 V) exp(-t/2 s)

For t >3 s:
iL = 0.44 A + 1.56 A (1-exp(-[t-3 s]/1 s)
VL = (3.11 V) exp(-[t-3 s]/1 s)

Transient current through inductor

Transient voltage across inductor
