Current in a RL Circuit Calculator

The Current in a RL Circuit Calculator will calculate the:

The current flowing at any instant in a RL circuit when the current in the circuit is increasing
The current flowing at any instant in a RL circuit when the current in the circuit is decreasing

Calculation Considerations: The conducting wire of circuit and material the inductor is made from are both uniform and they have the same thickness everywhere; the source supplies DC current
