The current through a 5-mH inductor is shown in the Figure. Determine the sign and magnitude of the voltage across the inductor at t = 5 ms. Enter your answer in magnitude of volts with the current sign.

To measure the capacitance C of a capacitor, you attach the capacitor to a battery and wait until it is fully charged. You then disconnect the capacitor from the battery and let it discharge through a resistor of resistance RR. You measure the time T1/2 that it takes the voltage across the resistor to decrease to half its initial value at the instant that the connection to the capacitor is first completed. You repeat this for several different resistors. You plot the data as T1/2 versus R and find that they lie close to a straight line that has slope 9.00 μF. What is the capacitance C of the capacitor?

At 0-, no currrent flows through the capacitors because they are open, how did you combine the capacitors for the voltage divider since it is the capacitance value and not reactance, is it right? Can we just combine the capacitance value? Please explain. I did not understand..

Two capacitors A and B having capacitance of 20uF and 30uF respectively are connected in series to a 600v supply. Determine the p.d across each other. If a third capacitor C is connected in parallel with A and it is found that p.d across B is 400v, calculate the capacitance of C and energy stored in it

.A series RLC circuit contains a 4-kN resistor, an inductor with an inductive reactance (X,) of 3.5 kn, and a capacitor with a capacitive reactance (Xc) of 2.4 kN. A 120-Vac, 60-Hz power source is connected to the circuit. How much voltage is dropped across the inductor?

A 10¯7-F capacitor (100 nanofarads) is charged to 100 V and then disconnected. One can model the charge leakage of the capacitor with a RC circuit with no voltage source and the resistance of the air between the capacitor plates. On a cold dry day, the resistance of the air gap is 3× 103 Q; on a humid day, the resistance is 8 x 10° Q. How long will it take the capacitor voltage to dissipate to half its original value on each day?
