The shown alternating current circuit has a resistance less coil L and a resistance R. The potential difference across the choke is V L = 160 volt and the potential difference across the resistance is V R = 120 volt. Find the virtual value of the applied voltage. If the virtual current in the circuit is 1.0 ampere, then calculate the total impedance of the circuit. If a direct current be passed in the circuit, then what will be the potential difference in the circuit?
