The voltage across a 0.6μF capacitor is zero for t<0. For t≥0, the voltage is 40e−15,000tsin30,000t V. a. Find the initial current in the capacitor in the direction of the voltage drop. b. Find the power delivered to the capacitor at t=π/80 ms. c. Find the energy stored in the capacitor at t=π/80 ms.
