Find Multimeter Voltage Range. Get Voltage Multimeter. Voltage is the force that makes electricity move, so detecting voltage can help you figure out if a component is working as intended.
The simplest way to test voltage is by using a digital multimeter that automatically adjust to the correct test settings. A typical multimeter can measure voltage, current, and resistance.

Analog multimeters use a microammeter with a moving pointer to display readings. If you have a multimeter in your house then, this operation will so easy to do. If you did not have a multimeter then purchase one from the market. In the multimeter voltage section, use the part labeled V and a straight line to measure DC voltage.
