Correct option is C
In an AC (Alternating Current) circuit, the total opposition to the flow of current is called
impedance. Impedance is a complex quantity that combines both resistance (the opposition to current in a DC circuit) and reactance (the opposition to current caused by inductors and capacitors in an AC circuit). It is represented by the symbol Z and is measured in ohms (Ω).
·
Inductance and
Capacitance contribute to the reactance in the circuit but do not represent the total opposition by themselves.
·
Resistance is the opposition to current in a DC circuit or the real part of impedance in an AC circuit.
Thus, impedance is the correct term for the total opposition in an AC circuit.
