An AC series RC circuit is made up of a resistor that has a resistance value of 20 Ω and a capacitor that has a capacitive reactance value of 30 Ω. Calculate the impedance and the phase angle theta (θ) of the circuit.
Impedance (Z) of a series R-C circuit may be calculated, given the resistance (R) and the capacitive reactance (X C). Since E=IR, E=IX C, and E=IZ, resistance, reactance, and impedance are proportional to voltage, respectively. Thus, the voltage phasor diagram can be replaced by a similar impedance diagram.
If the total impedance in a series circuit with both inductive and capacitive elements is less than the impedance of either element separately, then the total current in that circuit must be greater than what it would be with only the inductive or only the capacitive elements there.
Because the resistor’s resistance is a real number (5 Ω ∠ 0°, or 5 + j0 Ω), and the capacitor’s reactance is an imaginary number (26.5258 Ω ∠ -90°, or 0 - j26.5258 Ω), the combined effect of the two components will be an opposition to current equal to the complex sum of the two numbers.
(The phase angles of resistive and capacitive impedance are always 0° and -90°, respectively, regardless of the given phase angles for voltage or current.) As with the purely capacitive circuit, the current wave is leading the voltage wave (of the source), although this time the difference is 79.325° instead of a full 90°.
Impedance is the total measure of opposition to electric current and is the complex (vector) sum of (“real”) resistance and (“imaginary”) reactance. Impedances (Z) are managed just like resistances (R) in series circuit analysis: series impedances add to form the total impedance.

Perhaps the first practical issue we face is determining the effective impedance of an RLC series loop. For starters, resistors in series simply add.
