Voltage is the difference in electric potential energy between two points in a circuit. Voltage is measured in volts (V). The voltage between two points is equal to the work done per unit charge moving between those points.

##### What is voltage & current?

Voltage is the difference in electric potential between two points. The unit of voltage is the volt (V).

Current is the rate of flow of electric charge. The unit of current is the ampere (A). What is the voltage of electricity? Electricity is the flow of electrical charge. This flow is typically measured in volts. The voltage of electricity refers to the potential difference between two points in a circuit. In other words, it is the difference in electric potential energy between two points in a circuit. The SI unit for voltage is the volt (V). Why is it called voltage? Voltage is the difference in electrical potential between two points. It is measured in volts. The term voltage is derived from the Latin word for "volt," which is voltus. What is voltage in a battery? Voltage in a battery refers to the amount of electrical potential energy that the battery can store. This is measured in volts and is determined by the number of cells in the battery. The more cells a battery has, the higher its voltage will be.

### What are types of voltage?

There are two main types of voltage: direct current (DC) and alternating current (AC).

DC voltage is a constant voltage that flows in one direction only. DC voltage is typically generated by batteries and solar panels.

AC voltage is a voltage that alternates between positive and negative values. AC voltage is typically generated by power plants and household appliances.
