Tutorial on setting up the multimeter for start measuring the voltage[edit]

1. Get the Multimeter
get a multimeter
2. Get the Red and black voltmeter probe cable
voltmeter probe cables
3. Plug them in the multimeter. The Black voltmeter probe cable needs to be plugged in the "COM" which stands for "COMMON". The Red voltmeter probe cable needs to be plugged in the "VΩmA"

4.Turn on the multimeter to 20 Direct Current Voltage

5. One is ready to take measure voltage by touching two points in the circuit. A negative number means that the electromotive force is higher where the black probe is touching.
