A load has a 20 ohm resistor and a 4 henry inductor connected in series.

A load has a 20 ohm resistor and a 4 henry inductor connected in series. It is connected to a power source with v(t)= 100cos50t, connected in series to the load. What is the impedance, the current, and the average power delivered to the load using the phasor transform method.

If a current i = 40cos(100t +20) is fed through a 1/10F capacitor, what is the voltage, instantaneous power and average power.

If a current i = 40cos(100t +20) is fed through a 1/10F capacitor, what is the voltage, instantaneous power and average power.

Capacitor discharging thru a resistance.

At time t=0, the voltage across a capacitor rated at 3/10 F is 10V. a switch is closed and the capacitor is in series with a resistor r=50 ohms. How long does it take for the voltage to decay to 4 volts?
