What is Class 12 Physics: Alternating Current Notes about?
1) Alternating current is a current whose magnitude and direction change periodically with time. The instantaneous value of AC is defined as its value at a given instant, while the peak value is the maximum value in a cycle. The root-mean-square (RMS) value is 0.707 times the peak value and represents the effective or apparent value. 2) In an AC circuit, the phase difference between the voltage and current depends on whether the circuit has resistance, inductance, or capacitance. For a pure inductor the c
