resistor and a capacitor with 150 of capacitive reactance are in series across an ac source. The impedance, expressed in rectangular form, isZ = 47 + j150
+ j150 Z = 47 – j150
– j150 Z = 197
Z = 103

Z = r + jx.
For capacitive reactance.
Z = r - jx.
For inductive reactance.
For capacitive reactance.
Z = r - jx.
For inductive reactance.

@Indrejit you are wrong.
For inductive Z = R+jXl.
For capacitive Z = R-jXc.
For inductive Z = R+jXl.
For capacitive Z = R-jXc.

In series RC circuit : (R-jXc).
In parallel RC circuit: ( R+jXc).
In parallel RC circuit: ( R+jXc).

Z=R-jXc
Z=47-j150 ohms
Z=47-j150 ohms
