Questions & Step-by-Step Solutions

What is the role of a capacitor in an AC circuit? (2023)
  • Step 1: Understand that a capacitor is a device that can store electrical energy.
  • Step 2: In an AC (Alternating Current) circuit, the current changes direction periodically.
  • Step 3: When the AC voltage increases, the capacitor charges up and stores energy.
  • Step 4: When the AC voltage decreases, the capacitor releases the stored energy back into the circuit.
  • Step 5: This process helps to smooth out the flow of electricity and can improve the performance of the circuit.
