Impedance of a capacitor in series with a resistor

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.

How to calculate impedance of a series R-C 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.

What if the total impedance of a series circuit is less than capacitive?

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.

What is the difference between a resistor and a capacitor?

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.

What is the difference between resistive and capacitive impedance?

(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°.

What is impedance in circuit analysis?

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.

What is the combined effect of resistor and capacitor?

Because the resistor\’s resistance is a real number (5 Ω ∠ 0 o, or 5 j0 Ω), and the capacitor\’s reactance is an imaginary number (26.5258 Ω ∠ -90 o, 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.
