s-domain Method Summary

1.

Determine the initial conditions (capacitor voltage or inductor current at time t=0^-).

2.

Determine the s-domain representations for each circuit element.

3.

Draw the s-domain circuit.

4.

Using KCL/KVL, etc, solve for the desired current or voltage in the s-domain.

5.

Transform back to the time domain making use of know LT pairs, and if necessary, partial fractions.

6.

Check your answer.
