Questions and Answers

What is the behavior of a diode when it is forward biased?

  • It behaves as a resistor and reduces the current flow
  • It behaves as a closed switch and allows current to flow (correct)
  • It behaves as a capacitor and stores the current
  • It behaves as an open switch and does not allow current to flow

    • What is the behavior of a diode when it is reverse biased?

  • It behaves as a closed switch and allows current to flow
  • It behaves as a resistor and reduces the current flow
  • It behaves as an open switch and does not allow current to flow (correct)
  • It behaves as a voltage source and supplies current

    • Why is it necessary to convert AC voltage into DC voltage for electronic gadgets like TV and mobile chargers?

  • AC voltage is cheaper than DC voltage
  • AC voltage is more stable than DC voltage
  • Electronic gadgets only work with DC voltage (correct)
