What Is Volt (V)?
As with a car's gas gauge, a #Volt (or "V" for short) indicates how much juice the battery still has left. A volt is a measure of electric potential difference; it determines how much "juice" a given circuit has. Consider the fuel gauge in your car; it indicates how much energy is left in the battery. A circuit's voltage, or volts, is analogous to a car's fuel level indicator; it shows the amount of "energy" (or electrical potential) available to drive the circuit's components. The first practical electrical battery is attributed to the Italian physicist Alessandro Volta, for whom the unit volt is named. Volt was created in 1881 by the International Electrical Congress to commemorate his work in the field of electricity. Electrical potential between two points in a circuit, measured in volts, sufficient to force one ampere of current through a resistance of one ohm is called a volt. The volt is the standard unit of measurement for the energy required to drive an electric charge through a circuit. More voltage means more energy can be used to run the circuit. It's also important to note that voltage can be considered the "electromotive force" or "EMF" between two points in a circuit since it quantifies the amount of energy per unit charge available to move electric charge. Therefore, a higher voltage means more energy is available per charge to propel the electric demand along the circuit. A volt is a unit of measurement for electric potential difference and can be thought of as the equivalent of a fuel gauge for a car's battery because it reveals how much "juice" is present in a given circuit. A unit of electric potential between two points in a circuit that can generate one ampere of current through a resistance of one ohm; it was named after the Italian physicist Alessandro Volta. Also known as electromotive force (EMF), this energy per unit charge can be used to transfer an electric charge from one location to another in an electrical circuit. #electronics #electricity
