Opposition to the flow of direct current caused by resistance
Opposition to the flow of alternating current caused by capacitance or inductance✓الإجابة الصحيحة
Reinforcement of the flow of direct current caused by resistance
Reinforcement of the flow of alternating current caused by capacitance or inductance
الشرح
Reactance is the frequency-dependent opposition that inductance and capacitance present to alternating current; it opposes current rather than reinforcing it, which rules out the two reinforcement choices. Opposition caused by resistance is resistance, not reactance.
