Voltage Current Definition

In this analogy charge is represented by the water amount voltage is represented by the water pressure and current is represented by the water flow.

Voltage current definition. The current is the number of coulombs of charge passing by that point per second. Voltage is represented in equations and schematics by the letter v. Voltage is defined so that negatively charged objects are pulled towards higher voltages while positively charged objects are pulled towards lower voltages. When describing voltage current and resistance a common analogy is a water tank.

In many cases a stronger electric force meaning a higher voltage produces a higher current because the charges are pulled faster toward ground. Current is the rate at which electric charge flows past a point in a circuit. There are multiple useful ways to define voltage including the standard definition mentioned at the start of this page. It says that the current is equal to the voltage divided by the resistance or i v r.

Voltage is what makes electric charges move. There are also other useful definitions of work per charge see this section. There is a basic equation in electrical engineering that states how the three terms relate. The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size.

How to use voltage in a sentence. Voltage definition is electric potential or potential difference expressed in volts. In other words current is the rate of flow of electric charge. Current voltage and resistance current is the rate of flow of electric charge.

In particular we define current at a specific point. Voltage also called electromotive force is the potential difference in charge between two points in an electrical field. So for this analogy remember. Voltage also called electromotive force is a quantitative expression of the potential difference in charge between two points in an electrical field.

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. Electric power like mechanical power is the rate of doing work measured in watts and represented by the letter p the term wattage is used colloquially to mean electric power in watts the electric power in watts produced by an electric current i consisting of a charge of q coulombs every t seconds passing through an electric potential difference of v is.
