What is this Impedance Calculator?

The Impedance Calculator helps users calculate the total impedance of an AC circuit that contains resistance, inductive reactance, and capacitive reactance. By entering the values for resistance (R), inductive reactance (Xₗ), and capacitive reactance (Xc), the tool computes the circuit’s impedance according to the formula Z=R2+(XL−XC)2Z = \sqrt{R^2 + (X_L – X_C)^2}Z=R2+(XL−XC)2. This ensures accurate understanding of AC circuits, making it useful for students, engineers, and anyone working with electrical systems.

How to Use:

Enter Resistance (R, ohms): Input the resistance value of the circuit in ohms.
Enter Inductive Reactance (Xₗ, ohms): Input the inductive reactance of the circuit in ohms.
Enter Capacitive Reactance (Xc, ohms): Input the capacitive reactance of the circuit in ohms.
Click “Calculate”: The calculator computes the total impedance using the formula Z=R2+(XL−XC)2Z = \sqrt{R^2 + (X_L – X_C)^2}Z=R2+(XL−XC)2.
Review Result: The output shows the impedance in ohms, along with a prompt if invalid values are entered, helping you understand the effective opposition to AC current safely and clearly.
