1. The problem statement, all variables and given/known data A circuit consists of a 50nF capacitor in series with a 47kΩ resistor. An AC voltage of 120Vrms at 350Hz is applied to the circuit. (a) Determine the current flowing through the circuit. (b) Sketch the impedance diagram for the circuit at this frequency. 2. Relevant equations Xc , diagram , V = IZ 3. The attempt at a solution First i found Xc = 1/2* pi* f * C Then i did impedence diagram to find z and then use V = IZ to find Z I got the answer: 2.51mA But why it says answer is : 3.545sin(700π+11^0)mA ????
