A simple process to solve any resistor-inductor linear circuit
More examples using the simple process
Description
Day 28 of Linear Circuits. Inductors are one of the three passive circuit components (along with resistors and capacitors). However, their operation and behavior is often shrouded in mystery. After seeing how to find the initial and final values of currents and voltages, today, we introduce a solution process that uses this information for any resistor-inductor circuit. Here, we include even more examples of using our process to solve resistor-inductor circuits.
The material covers all of the lecture material from an twenty-eighth lecture in a traditional, sophomore-level linear circuits class.
