What Does Voltage Mean In Electricity

Voltage electric potential difference electric pressure or electric tension is the difference in electric potential between two points which in a static electric field is defined as the work needed per unit of charge to move a test charge between the two points.

What does voltage mean in electricity. When we do experiments with electricity we use small batteries. The greater the voltage the greater the flow of electrical current that is the quantity of charge carriers that pass a fixed point per unit of time through a conducting or semiconducting medium for a given resistance to the flow. Voltage is the pressure from an electrical circuit s power source that pushes charged electrons current through a conducting loop enabling them to do work such as illuminating a light. The term recognizes italian physicist alessandro volta 1745 1827 inventor of the voltaic pile the forerunner of today s household battery.

An electric current can now flow along the wire. The standard electrical dictionary 1 00 1 vote rate this definition. What does voltage mean. We describe this as the voltage of the battery.

In the international system of units the derived unit for voltage potential difference is named volt. This voltage is printed on the side of the battery. In brief voltage pressure and it is measured in volts v. The voltage of the power line to your home is much higher.

Voltage also called electromotive force is a quantitative expression of the potential difference in charge between two points in an electrical field.
