None of the above” correct=”option1″]
The correct answer is: A. equal to the sum of the individual capacitive-reactance values.
Capacitive reactance is the opposition to the flow of alternating current (AC) in a capacitor. It is measured in ohms (Ω) and is inversely proportional to the capacitance and frequency of the AC signal.
The total capacitive reactance of a parallel capacitor circuit is equal to the sum of the individual capacitive-reactance values. This is because the capacitors in parallel are all connected to the same voltage source, and the current through each capacitor is independent of the current through the other capacitors.
Option B is incorrect because the total capacitance of a parallel capacitor circuit is equal to the sum of the individual capacitance values.
Option C is incorrect because the total current in a parallel capacitor circuit is equal to the sum of the individual currents through each capacitor.
Option D is incorrect because the total capacitance of a parallel capacitor circuit is always greater than the capacitance value of the smallest capacitor.
Option E is incorrect because the total capacitive reactance of a parallel capacitor circuit is always equal to the sum of the individual capacitive-reactance values.
