Impedance in Voltmeter Formulas

Impedance is a measure of the opposition that a circuit presents to the flow of alternating current consisting of both resistance and reactance. And is denoted by Z. Impedance is usually measured using the Ohm for Electric Resistance. Note that the value of Impedance is always positive.

FAQ

What is the Impedance?

Impedance is a measure of the opposition that a circuit presents to the flow of alternating current consisting of both resistance and reactance. Impedance is usually measured using the Ohm for Electric Resistance. Note that the value of Impedance is always positive.

Can the Impedance be negative?

No, the Impedance, measured in Electric Resistance cannot be negative.

What unit is used to measure Impedance?

Impedance is usually measured using the Ohm[Ω] for Electric Resistance. Megohm[Ω], Microhm[Ω], Volt per Ampere[Ω] are the few other units in which Impedance can be measured.
