What Is Voltage Simple Definition

Voltage is a representation of the electric potential energy per unit charge.

What is voltage simple definition. 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. A simple analogy for an electric circuit is water flowing in a closed circuit of pipework driven by a mechanical pump. During early days of electricity voltage was known as electromotive force emf this is why in early formulas as ohm s law voltage is represented by the symbol e in modern days it is represented by the symbol v or e. Example of voltage in a simple direct current dc circuit.

Voltage is what makes electric charges move. In other words it is a measurement of the energy contained within an electric field or an electric circuit at a given point it is equal to the work that would have to be done per unit charge. At the beginning of the circuit electricity has a certain amount of force. In this dc circuit the switch is closed turned on.

The voltage between two ends of a path is the total energy required to move a small electric charge along that path divided by the magnitude of the charge. The greater the amount of charge and the greater the physical separation the greater the voltage or stored energy. It is the push that causes charges to move in a wire or other electrical conductor it can be thought of as the force that pushes the charges but it is not a force voltage can cause charges to move and since moving charges is a current voltage can cause a current. How to use voltage in a sentence.

Voltage also called electromotive force is a quantitative expression of the potential difference in charge between two points in an electrical field. It also has a. Voltage in the power source the potential difference between the battery s two poles is activated creating pressure that forces electrons to flow as current out the battery s negative terminal. If a unit of electrical charge were placed in a location the voltage indicates the potential energy of it at that point.
