Questions and Answers

What happens to the voltage across the inductor just before the switch opens?

  • It becomes zero. (correct)
  • It reaches a constant value.
  • It is equal to the current through the resistor R(0).
  • It doubles in magnitude.

    • How does the inductor behave just before the switch opens?

  • Like an open circuit.
