What Is Voltage Simple Definition

Voltage definition is electric potential or potential difference expressed in volts.

What is voltage simple definition. How to use voltage in a sentence. It is produced when you have generated a dc waveform from an ac using a rectifier. Voltage is a representation of the electric potential energy per unit charge. If a unit of electrical charge were placed in a location the voltage indicates the potential energy of it at that point.

A simple analogy for an electric circuit is water flowing in a closed circuit of pipework driven by a mechanical pump. 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. Voltage also called electromotive force is a quantitative expression of the potential difference in charge between two points in an electrical field. Voltage is what makes electric charges move.

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. How is voltage measured. 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. As the name suggests ripple voltages are the ones not having a constant magnitude they are undulations on a dc waveform.

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. 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. Ripples tend to reduce the efficiency of. Voltage drop specifies the amount of electric power produced or consumed when electric current flows through the voltage drop.

In this dc circuit the switch is closed turned on. A simple example of a voltage divider is two resistors connected in series with the input voltage applied across the resistor pair and the output voltage emerging from the connection between them. Voltage drops can be measured in a circuit with an appropriate. Example of voltage in a simple direct current dc circuit.
