find the r.m.s. value of the voltage and current




The voltage given by V = 100 cos 314 t + 50 sin (1570 t – 30o) is applied to a circuit consisting of a 10 ? resistor, a 0.02 H inductance and a 50 µF capacitor. Determine the instantaneous current through the circuit. Also find the r.m.s. value of the voltage and current.
