This circuit consists of a resistor in series with a battery and a switch. You can open and close the switch by dragging the lever up and down.
The multimeter and its probes can be moved by dragging them with the mouse. To make a measurement, move the leads of the multimeter and touch them to any of the little circles on the circuit. Rotate the dial on the multimeter to turn it on and set its mode. Right-click on the multimeter to make it bigger.

Using a Multimeter

This is a test to see whether you know how to use a digital multimeter.

On the next screen, you will watch a short movie demonstrating the activity. Then you will see a simulated multimeter and a circuit consisting of a resistor in series with a battery and a switch. You will be asked to make various measurements using the multimeter.

Make your measurements as quickly and efficiently as possible without being sloppy. You will be evaluated not only on your answers but on how did you use the multimeter to obtain them.

When you finish the test, click the report button to see your score.
