Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Impedance in the alternating current circuit is defined as the net opposing factor to the flow of current.
This opposition may be due to Resistance & Inductance or Resistance & Capacitance or Resistance, Inductance and Capacitance.
It is denoted by the symbol Z.
Z is often expressed as Z = R+jX
Calculation:
Given;
Z = -2jΩ = 2∠-90°
θv - θi= -90°
∴ phase difference between voltage and current is -90°
