Countervoltage presented by a capacitor is called _____.
A) capacitance
B) inductance
C) capacitive reactance
D) inductive reactance
Countervoltage
A voltage that opposes the primary voltage source in a circuit, often referred to as back EMF (Electromotive Force).
Capacitive Reactance
The resistance that a capacitor offers to the flow of alternating current (AC) in an electrical circuit, which varies inversely with the frequency of the current and the capacitance of the capacitor.

Final Answer :
C
Explanation :
Capacitive reactance is the term used to describe the opposition to the change of voltage across an element, in this case, a capacitor. It is a measure of how a capacitor resists or reacts to alternating current (AC) at a particular frequency, not to be confused with capacitance, which is a measure of a capacitor's ability to store charge.
