Answer:
D
Step-by-step explanation:
The total opposition to the flow of alternating current (AC) in an electric circuit is called impedance. Impedance includes both resistance (opposition to the flow of current in a resistor) and reactance (opposition due to capacitance and inductance). Impedance is a complex quantity and is represented by a complex number, where the real part corresponds to resistance, and the imaginary part corresponds to reactance.
