Volt

Figure 1. These are examples of various batteries that hold a voltage of 1.5[1]

The volt is the SI unit that measures voltage difference or potential difference between two points on a conductor. The symbol for volt is V.[2] The volt can be thought of as a J/C because the voltage indicates how much energy would be gained by transporting a given amount of electric charge (in coulombs).

Some typical voltages include: 1.5 V on C, D, AA, and AAA batteries (see figure 1); 9 V on 9 V batteries and 120 V on North American electrical outlets.

To learn more about the volt please see Dr. Rowlett's dictionary of units.
