The multimeter is a important piece of equipment if you want to experiment with electronics or build electronic circuits. This module discusses what a multimeter is used for and how to use one.
One of the uses for a multimeter is to measure electical resistance in an electrical circuit. This module discusses concepts such as resistor color coding as well as parallel and serial reistance. It also provides some insights on how a multimeter is used to measure resistance:
Electrical voltage is the electrical "pressure" in a circuit. This module discusses the basics of electrical voltage and provides an introduction to batteries as well as pointers on how to use a multimeter to measure voltage:
Electrical current is the quantity of electrical charge that passes through a wire in a given time. This module addresses the basics of electical current and how a multimeter can be used to measure it:
This module discusses how to design and build a small water-driven power generating station. A hand-driven test apparatus is built to test concepts, experiments are developed to create analytical tools, and the final system is tested:
