Impedance in an AC Circuit

Introduction to Impedance in an AC Circuit

The impedance in an AC circuit is the total opposition that a circuit offers to the flow of alternating current. It is a combination of resistance (R) and reactance (X). The formula for calculating impedance is Z = √(R^2 + X^2), where Z represents impedance, R is the resistance, and X is the reactance. The impedance is usually expressed in ohms (Ω).

Parameter usage:

• R= resistance in ohms (Ω)
• X= reactance in ohms (Ω)

Data validation

The resistance and reactance values must be non-negative.

Summary

This formula calculates the impedance in an AC circuit based on the resistance and reactance.
