Resistor Circuits - Practice Exercises

Try Each Problem Below - Some Practice Exercises For You

Suggestion

First sketch a circuit diagram on a piece 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.

Place your cursor over the antenna symbol to check your answer. The correct solution will appear. You don't have to click. If this method does not work, the answers for each question, follows at the end of the questions.
