This item is one segment of a two-part lab designed to help students become comfortable with using a multimeter. In this segment, users explore how to measure current, the rate of electron flow in a circuit. It contains explicit instructions on how to connect a battery to an incandescent lamp and use test probes to measure current. Teachers may extend the activity with a breadboard or terminal strip. Detailed diagrams are provided for each phase of the experiment.
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.

Topic: Electricity and Electrical Energy
Unit Title: Applying Concepts of Electricity
This is a companion lab to the resource directly above, "Voltmeter Usage". It helps students get practice in using the ammeter function of a multimeter to measure current -- the rate of electron flow in a circuit. Detailed instructions and photos make set-up easy.Link to Unit:
