This classroom lab reinforces student understanding of circuit continuity. A lamp is connected to a battery with jumper wires. After measuring normal voltages in a functioning circuit, students break the circuit at each of the four connecting points, then remeasure. For more advanced learners, the same circuit can be constructed on a breadboard or measured across a terminal strip. Detailed diagrams enable easy set-up.
This resource was developed to supplement the free textbook series All About Circuits, part of the Open Book Project. Each chapter is supplemented with related diagrams, photos, and detailed explanations of mathematical formulas.

A very effective lab for reinforcing the importance of circuit continuity. A lamp is connected to a battery with jumper wires. After measuring normal voltages in a functioning circuit, students break the circuit at each of the four connecting points, then measure again. Editor's Note: For additional practice in measuring voltage, see "Voltmeter Usage" activity below.
