Question 197Electricity/Electronics - Assistant Engineer70% 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. Ohms are the standard unit of measure for all types of electrical impedance, including resistance, inductive reactance, and capacitive reactance. This is in accordance with the fundamental principles of electrical engineering and the regulations governing the US Coast Guard Captain's License Examinations.
The other options are incorrect because: A) farads measure the unit of capacitance, B) mhos measure the unit of conductance, and D) henrys measure the unit of inductance, none of which directly correspond to the measurement of capacitive reactance.
