Resistor Circuits - Practice Exercises **

Try each problem below - some practice exercises for you!

Suggestion: First sketch a circuit diagram on a scrap of paper. Enter the information that you are given. Write down what you have to find too - the missing information. Then decide how the various Ohm's Law formulas can be used to find the solution.Nominal "names" are given in these circuits to identify the current, the voltage and the resistors themselves.

To check your answer:Place your cursor over the antenna symbol alongside. The correct solution will appear!You don't have to click.
