Problem 31.12: Determine value of inductor and power in RL circuit
− VS | − I | − VR | − VL
Please wait for the animation to completely load.
Assume an ideal power supply. The graph shows the voltage across the source (red) and the current (black) through the circuit as a function of time, as well as the voltage across the resistor (blue) and the voltage across the inductor (green) (voltage is given in volts, current is given in milliamperes [mA = 10-3 A], and time is given in seconds). Restart.
- What is the value of the unknown inductor?
- What is the average power dissipated when the reactance of the inductor equals the resistance of the resistor?
