Voltage Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points. The voltage between two points is equal to the work done per unit of charge against a static electric field to move a test charge between two points. This is measured in units of volts; moving 1 coulomb of charge across 1 volt of electric potential requires 1 joule of work. Voltage differences between points can be caused by static electric fields, by electric

What is the difference between voltage and current? Voltage is a force that makes electricity move through a wire. It is measured in volts. Voltage is also called electric tension or electromotive force (EMF). It was named after Alessandro Volta. Technically, the voltage is the difference in electric potential between two points. Voltage is always measured between two points, for example between the positive and negative ends of a battery, or between a wire and ground.

- An ampere, or amp (A or I, for current), is the amount of current in a circuit, while voltage (V) is the strength of the current as it flows through the circuit, and watts (W) are the total electrical power released by circuit per second.lectricity is simply a motion of a certain size. The voltage is the difference between the motion in point a and b. The current, or amps, is the speed of the motion through the wire. The shape of the circuit determines the speed at which the motion will travel from point a to b.

Voltage divider In electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (V out) that is a fraction of its input voltage (V in). Voltage division is the result of distributing the input voltage among the components of the divider.

Calculating Series Voltage Drop Series voltage drop is the progressive loss of voltage that occurs when feeding a string of parallel-connected loads. It's of particular concern when feeding a string of roadway, walkway, or parking lot lamps (Photo). These situations definitely call for calculations to determine the voltage drop at the last luminaire.

volt One volt is the potential difference between two points on a conductor when the current flowing is 1 ampere and the power dissipated between the points is one watt (definition adopted by the CIPM in 1946, Resolution 2). It is named for the Italian physicist Count Alessandro Giuseppe Anastasio Volta (1745 – 1827).

- Voltage is the measure of the strength of an electrical source (for a given current level). Rechargeable batteries for power tools generally contain cells with a voltage of 1.2V, 1.5V or 3.6V.atteries that have a voltage between 14.4V and 36V are manufactured for use on heavier duty tools such as cordless hammer drill drivers, cordless angle grinders, and cordless circular saws. The most common voltage used amongst manufacturers (due to its weight, cost, and potential power output) is 18V.

Voltage Voltage is electric potential energy per unit charge, measured in joules per coulomb (= volts). It is often referred to as electric potential, which then must be distinguished from electric potential energy by noting that the potential is a per-unit-charge quantity.he electric field is not the only factor determining charge flow in a material, and different materials naturally develop electric potential differences at equilibrium (Galvani potentials). The electric potential of a material is not even a well defined quantity, since it varies on the subatomic scale.
