Alternating Current Lec -3 | AC Circuits and AC through a Resistor | 2nd Year FSc Physics

A pure resistive circuit has only a resistor connected with an AC source and has a phase difference of zero between alternating voltage and current. An AC circuit has either a resistor, a capacitor, or an inductor connected with an AC source or combination of any of the said two. For a purely resistive circuit, the instantaneous value of voltage and current varies in phase i.e the current is zero at the moment the voltage is zero across the resistor and is maximum at the instant the voltage is maximum. The power output of a purely resistive circuit can be found by multiplying V and I at any instant. Watch the lecture for complete detail of the topic.
