If a circuit has a resistance of 3002 and a series inductance of 5002, what is the relationship between the applied circuit voltage and the circuit current? The applied voltage lags the circuit current. The phase shift between the circuit voltage and current changes with time. The applied voltage is in phase with the circuit current. The applied voltage leads the circuit cur Previous Page Next Page Page 2 of 10
