Question 96Electricity/Electronics - QMED70% to pass
AC circuits can possess characteristics of resistance, inductance, and capacitance. In terms of units of measure, how is the capacitive reactance of the circuit expressed?
AI Explanation
The correct answer is C) ohms.
Capacitive reactance, which is the opposition to the flow of alternating current (AC) in a capacitive circuit, is measured in ohms. This is because capacitive reactance is inversely proportional to the capacitance of the circuit and the frequency of the AC signal, and the unit of measurement for this relationship is ohms.
The other options are incorrect because:
A) mhos is the unit of measure for conductance, not capacitive reactance.
B) henrys is the unit of measure for inductance, not capacitive reactance.
D) farads is the unit of measure for capacitance, not capacitive reactance.
