1.) A time of 13 milliseconds is required for the current on a series RL dc circuit to reach 58% of its final steady state value. Assume at t = 0, i(0) = 0. What is the value of R if the inductor is 5 H? 2.) An uncharged capacitor in series with a 120-volt voltmeter of 12,000 ohms resistance is suddenly connected to a 120 V battery. One second later, the voltmeter reads 50 volts. Determine the capacitance of the capacitor. 3.) A series RC circuit consist of R = 2200 k and an uncharged capacitor C = 5 uF. The circuit is connected across a 120 V DC source at t = 0. Determine the voltage across the resistor 4.6 seconds later. 4.) A series RLC circuit with R constant voltage V = equation at any time. = 3000 ohms, L= 10 H, C = 200 microfarad has a 50 volts applied at t = 0. Find the resulting transient voltage
