Transient Analysis (Transient Response) of Series RL
Circuit using Oscilloscope
Objective:
To measure the “Time Constant” of RL circuit.
Apparatus:
Oscilloscope
Resistor 5Ω
Inductor 200mH
Connecting wires
Breadboard
Procedure:
1. Make a series RL circuit and apply DC voltage to it.
2. Choose the values of resister and inductor wisely to satisfy time constant condition i.e.,
τ = 5(L/R), so that resultant charging and discharging curve is visualized clearly. (In our case R =
5Ω and L = 200mH)
8. Use “Transient Analysis” from multiSIM to observe the voltage and current flowing through the
inductor.
9. Calculate the time constant τ = 5(L/R) by keeping the value of inductor fixed while changing the
value of resistor. Verify your results from scope .
10. Repeat whole process for different values of resistor and inductor.
