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).
