About This Resource

These are "endless" examples and exercises built on the DC power equations. Use them to sharpen your skills and build your intuitive sense.

Use a calculator to solve the problems on a separate sheet of paper. Click the Answer button to see the correct solution, then the Next button to see new problem.

Values are randomly selected, so it is unlikely you will see the same problem more than one time.
