SUMMARY

The discussion focuses on determining the current through an inductor as a function of time when a current pulse of 10.0A is applied for 200 microseconds. The relevant equation used is I = E/R(1 - e^(-t/T)), where E is the voltage, R is the resistance, and T is the time constant. The participants express uncertainty about the application of the equation and the need for a visual reference, specifically Figure P32.20, to clarify the circuit configuration.

PREREQUISITES
  • Understanding of inductors and their behavior in electrical circuits
  • Familiarity with the equation I = E/R(1 - e^(-t/T))
  • Knowledge of time constants in RC and RL circuits
  • Basic circuit analysis skills
NEXT STEPS
  • Study the behavior of inductors in transient circuits
  • Learn about the time constant (T) in RL circuits
  • Examine the effects of resistance (R) on inductor current
  • Review graphical representations of current over time in inductive circuits
USEFUL FOR

Students studying electrical engineering, physics enthusiasts, and anyone looking to understand transient responses in inductive circuits.

Homework Statement


A current pulse is fed to the partial circuit shown in Figure P32.20. The current begins at zero, becomes 10.0A between t=0 and t= 200microseconds and then is zero once again. Determine the current in the inductor as a function of time.


Homework Equations



I= E/R(1-e^-t/T)

The Attempt at a Solution



not really sure what to do here or if that is even the right equation to use.

Well, first you should show us Figure P32.20.
 
sorry, I was going to copy and paste it but it wouldn't let me so I had to do it myself.
