RC Circuits
A capacitor with 150Ω of capacitive reactance is across an ac source. The impedance, expressed in polar form, is

Z = 150 angle – 90° Ω
Z = 150
Z = 150 angle 180° Ω
Z = 150 –90° Ω

RC Circuits
A 47Ω resistor and a capacitor with 150Ω of capacitive reactance are in series across an ac source. The impedance, expressed in rectangular form, is

Z = 47Ω – j150Ω
Z = 197Ω
Z = 103Ω
Z = 47Ω + j150Ω
