termining the impedance and current of the system, the voltage across the resistor, and the voltage across the inductor.
Could you please forward the response as a print of a handwritten answer?
I got these two answers earlier. Which of them would be correct
Impedance Z= (1000 + j 90.836) ohm
Current I= 0.219∠-5.19° A
Voltage across resistor VR = 219.097∠-5.19° V
Voltage across inductor VL = 165.195∠84.81° V
Impedance will be Z= 1004.052 ∠ 5.12°
Current will be i = 0.221 ∠ -5.19° A.
Volatge across resistor will be VR = 211.9∠ -5.19° V
Volatge across inductor will be VL = 165.12 ∠ 84.81°V
