The average value of a complete cycle of AC is:

An AC current has an RMS value of 2A. What is the average value of the current over a full cycle?

An inductor of reactance $1\,\Omega$ and resistor of $2\Omega$ are connected in series. To the terminals of a 6v (rms) a.c. source. The power dissipated in the circuit is

What is the instantaneous value of an AC current at t = 0, if the equation is given by $I = 10\sin(100\pi t)$?

If the rms current in 50 Hz a.c. circuit is 5A, the value of the current 1/300 seconds after it’s value becomes zero is

For a purely resistive AC circuit, what is the phase difference between the voltage and current?

A $100\,\,W$ bulb produces an electric field of $2.9\,\,V/m$ at a point $3\,\,m$ away. If the bulb is replaced by $400\,\,W$ bulb without disturbing other conditions, then the electric field produced at the same point is

The instantaneous value of an alternating current is given by $i = 5sin(100\pi t)$. What is its peak value?

When the speed of a dc motor increases the armature current

Using an A.C. Voltmeter the potential difference in the electrical line in a house is read to be 234 volt. If the line frequency is known to be 50 cycles/second, the equation for the line voltage is.
