Q: Unit of impedance is……….
  • A. ohm
  • B. henry
  • C. tesla
  • D. hertz
Correct Answer: Option A - The impedance is the measure of the resistance of the current flowing in a circuit when the voltage is applied. It is denoted as 'Z'. Numerically Impedance of the composite voltage between the end of the circuit and composites are equal to the ratio of current. Unit of impedance are ohm. Impedance extends the concept of resistance to alternating current (AC) circuits and possesses both magnitude and phase unlike resitance, which has only magnitude.
