1. Question 1

   Q1. When a capacitor is connected in parallel with a resistor 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.
