What is the unit of measurement for measuring electrical pressure or EMF?

The symbol for volt is V. It is an SI unit, and it is the difference between force. The name is in honor of physicist Alessandro Volta.

The measurement was named after him because he invented the voltaic pile, which was the first chemical battery. There are common voltages in batteries we use every day. In our remote controls, alkaline batteries are used.

A single alkaline battery that is unable to be recharged has a volt of 1.5. Another common voltage is in a mercury battery, which normally has 1.355V. Many of our cars use batteries, and that battery has a voltage of 12 V.
