The resistor in this circuit has had its color bands rubbed off. Your job is to calculate its resistance. Unfortunately, the ohmmeter function on your digital multimeter (DMM) is broken. Work as efficiently as possible and do not damage your DMM.
Use the digital multimeter (DMM) to make measurements. Turn the dial to turn on the DMM and make it function as a voltmeter or an ammeter. Right-click the DMM to make it larger. Each time you make a measurement it will be saved in a lab notebook. You can look at the notebook to see all your measurements so far by clicking on the button.
When you think you know the answer, type it in the field below and click on the Submit Answer button.
You've connected the digital multimeter to the circuit. Remember, you can make it a voltmeter or an ammeter by turning the dial. If you're having trouble seeing it, you can make it bigger by right-clicking on it.

Measuring Resistance
On this test you will use a digital multimeter to determine the resistance of an unknown resistor. The catch is that the ohmmeter function of the multimeter is broken.
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.
Make whatever measurements and calculations you need to determine the resistance of the resistor. Do this as quickly and efficiently as you can without being sloppy. Each time you make a measurement it will automatically be stored in a lab notebook that you can view whenever you want. You can also use paper and pencil and a calculator, if you have one.
