1. The problem statement, all variables and given/known data A circuit contains two elements, but it is not known if they are L, R or C. The current in this circuit when connected to a 1.20×101 V, 60.0 Hz source is 4.70 A and lags the voltage by 4.20×101 degrees. a) What are the two elements? (Answer A,B or C) CL CR LR 2. Relevant equations Phasor diagram. V=IZ w = 2pi*f tan(theta)=XL - XC / R 3. The attempt at a solution From the phasor diagram for an AC circuit (or RLC circuit), usually the +y vector is for the inductor, the -y vector is for the capacitor, and the +x vector is for the resistor. Given that the phase angle is positive, I would say that the circuit is of type LR.
