Questions and Answers

What is the voltage across the resistor at t = 0+ if a unit step voltage is applied to a series RL circuit with zero initial conditions?

  • It is negative
  • It is infinite
  • It is equal to the applied voltage
  • It is zero (correct)
  • What happens to the current through the resistor in the steady state when a unit step voltage is applied to a series RL circuit with zero initial conditions?

  • It becomes infinite
  • It becomes oscillatory
  • It falls to zero
  • It reaches a constant value (correct)
  • Is it possible for the current to be oscillatory in a series RL circuit with zero initial conditions when a unit step voltage is applied?

  • Yes, if the inductance is very high
  • No, it is never oscillatory (correct)
  • Yes, if the resistance is very low
  • Yes, it is always oscillatory
  • What is the energy stored in the inductor in the steady state when a unit step voltage is applied to a series RL circuit with zero initial conditions?

    Study Notes

    Unit Step Voltage in a Series RL Circuit

    • A unit step voltage is applied to a series RL circuit with zero initial conditions at t = 0.
    • The inductor current is zero at t = 0- and t = 0+ (L(0^-)=0=L(0^+)).

    Voltage and Current in the Resistor

    • At t = 0+, the voltage across the resistor is zero (correct answer).
    • The resistor current does not necessarily fall to zero eventually (opposite of option D).

    Oscillatory Current and Energy Storage

    • The current in the circuit may or may not be oscillatory (option A is possible but not certain).
    • In the steady state, the energy stored in the inductor is not necessarily zero (opposite of option C).
