6 FAQs about [Series capacitor impedance]
Can a series capacitor cancel out a load impedance?
If the reactance (X) of the load impedance ZL is positive, then we can use a series capacitor to cancel out this reactance, making the input impedance purely real. As an example, let zL = 0.3 + i when f =500 MHz. Then we can cancel out the reactance with a series capacitor, determined by:
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 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.
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.
