Voltage is a measurement of potential electric energy between two points. You can measure the voltage of household circuitry or batteries using a digital multimeter, an analog multimeter, or a voltmeter. Most electricians and novices prefer a digital multimeter, but you can also use an analog multimeter.

What is used to measure voltage?

voltmeter, instrument that measures voltages of either direct or alternating electric current on a scale usually graduated in volts, millivolts (0.001 volt), or kilovolts (1,000 volts). ... The potentiometer operates by comparing the voltage to be measured with known voltage; it is used to measure very low voltages.

How do you measure voltage in a circuit?

To measure voltage on an electronic circuit, you don't have to insert the meter into the circuit. Instead, all you have to do is touch the leads of the multimeter to any two points in the circuit. When you do, the multimeter displays the voltage that exists between those two points.
