What Is the Formula for Impedance?

Answer

The formula for electrical impedance, which is denoted by the letter Z, is the square root of the total sum of the square of the resistance and the square of the inductance reactance. Impedance is the sum of all resistance in an electrical current. Electrical impedance is measured in Ohms, the S.I. unit for measuring electric charge.

Impedance (symbol Z) is a measure of the overall opposition of a circuit to current, in other words: how much the circuit impedes the flow of current. It is like resistance, but it also takes into account the effects of capacitance and inductance. Impedance is measured in ohms, symbol ohm. There are different formulas for impedance.
