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.
Xc , diagram , V = IZ
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 ????
