Physics · Alternating Current
An alternating current (a.c.) source of 15 V, 50 Hz is connected across an inductor (L) and a resistor (R) in series. An R.M.S. current of 0.5 A flows in the circuit. If the phase difference between the applied voltage and current is π3 radians, what is the value of the resistance (R)?
