The switch in Figure 7–6 closes at t = 0. For t ≥ 0 the current through the resistor is iRðtÞ = e^−100t mA.

(a) What is the capacitor voltage at t =0?

(b) Write an equation for υðtÞ for t ≥ 0.

(c) Write an equation for the power absorbed by the resistor for t ≥ 0.

(d) How much energy does the resistor dissipate for t ≥ 0?

(e) How much energy is stored in the capacitor at t =0?
