Exercise (RLC Series circuits – page 88)

ANSWER

1)
i(t) = 2 − 2e −6t
VR (t) = 120 − 120e −6t
VL (t) = 120e −6t

2)
i(t) = 2 − 2e −2t
i(t) =0.659Amps

3)
i(t) = 8e −4t
i(t) = 2.684mA

4)
i(t) = 10e −10t
i(t) = 0.498A
VR (t) = 4.98Volts
VC (t) = −4.98 Volts

5)
i(t) = −12e −4t + 15e −5t

6)
10 20
i(t) = − e −t + 10e −2t − e −4t
3 3
i(t) = 0.978 Amps
