STANDARD Physics Capacitive Reactance MCQ Question
In a pure capacitive circuit if the frequency of ac source is doubled, then its capacitive reactance will be
remains same
doubled
halved
zero
Correct Answer
Detailed Explanation
The capacitive reactance (X_C) is inversely proportional to the frequency (f) of the AC source, given by X_C = 1/(2πfC). Therefore, if the frequency is doubled, the capacitive reactance is halved.
