What effect will increasing the power source frequency have in a capacitive circuit?
AI Explanation
The correct answer is C) it will increase the average current in the circuit.
Increasing the power source frequency in a capacitive circuit will decrease the capacitive reactance, which in turn will increase the average current in the circuit. This is because the capacitive reactance is inversely proportional to the frequency of the power source. As the frequency increases, the capacitive reactance decreases, allowing more current to flow through the circuit.
The other options are incorrect because: A) increasing the frequency will affect the average current, B) it will increase the average current, not decrease it, and D) the capacitive reactance will decrease, not remain unchanged.
