  1. Question 1

    Q1. A resistor and capacitor are connected in parallel in an AC circuit. What phenomenon occurs due to the phase difference between voltage and current?

    • A) The current increases due to the capacitive reactance
    • B) The voltage across the resistor increases due to its impedance
    • C) The phase difference results in a resonant frequency, increasing the circuit's efficiency
    • D) The resistor's impedance causes a phase shift, making the circuit's current lag behind the voltage

    Answer: The current increases due to the capacitive reactance

    Explanation: The current increases due to the capacitive reactance, unlike the increased voltage or phase shift.
