Q.4Determine the current flowing in the capacitor(-j25ohm) and its direction as shown in Figure below. Assume the voltage source to have negligible impedance.

1) Propose and draw a circuit of a resistive current divider in half

Find the equivalent inductance as seen from the terminals shown in the figure.

True or false question. When a capacitor is charging, the voltage of the capacitor increases linearly (i.e., at a constant rate).

.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?

Find the Equivalent Capacitance between P and Q from the figure below

A utility company plans to connected a total of 20uF of capacitance to a 7,200 volt line. To make this connection, four capacitors will be connected in series. What is the capacitance of each capacitor?

An initially uncharged parallel plate capacitor is connected to a circuit containing a battery with emf -15V and a resistor, R = 8.5MN as shown in the figure to below. The capacitor whose plates have an area of A = 3.1mm² are separated by a distance of d = 3.4mm and one third of the capacitor is filled with a dielectric material, K₁= 1.1 and the rest (two thirds) is filled with another dielectric material, K₂=4.5. At t=0 the switch is closed. 7.1 seconds after the switch is closed the electric field within the first dielectric material (₁) is observed to be 15 x 10³ N/C.
