Under steady-state conditions, a capacitor acts as a. an open-circuit A 2-F capacitor is in parallel with a 4-V source. What is the energy (in joules) stored in the capacitor? e. 16 A 2-H inductor has been connected in series with a 4-V source and a 10-ohm resistor for a long time. What is the current (in amperes) in the inductor? e. 0.4 The voltage across an inductor is kept constant. What can be said about its current? Choose one answer. e. The current is changing linearly with time. The circuit is in equilibrium for t < 0, and the switch opens when t = 0. If Vo = 2 V, R = 2 ohms and C = 0.5 F, the voltage v(t) (in volts) for t > 0 is e. 2 e^(-t) The circuit is in equilibrium for t < 0, and the switch opens when t = 0. If Vo = 10 V, R1 = 2 ohms, R2 = 2 ohms and C = 0.5 F, the voltage v(t) (in volts) for t > 0 is c. 10 e-t/2
