Voltage. In the field of electronics, potential difference is commonly referred to as voltage and its symbol is V.In some cases, the symbol U or E for emf (electromotive force) is also used, but the standard symbol V represents any potential difference.This applies to the voltage generated by sources like battery or solar cell, and also to the voltage dropped across a passive electronic ...
An electron accelerated through a potential difference of 1 V is given an energy of 1 eV. It follows that an electron accelerated through 50 V is given 50 eV. A potential difference of 100,000 V (100 kV) will give an electron an energy of 100,000 eV (100 keV), and so on.

Potential difference is a scalar quantity. The other unit of potential difference is volt. 1 volt = 1 joule / coulomb. That is, If 1 joule / coulomb of work has to be done in taking a test charge from one point to another in an electric field, then the potential difference between those points will be 1 volt. If B is also at infinity then,
An electron accelerated through a potential difference of 1 V is given an energy of 1 eV. It follows that an electron accelerated through 50 V is given 50 eV. A potential difference of 100,000 V (100 kV) will give an electron an energy of 100,000 eV (100 keV), and so on.
This section explains energy transfers covering, power, potential difference and current equations, energy transfers in everyday appliances, work done and work done formula and the UK National Grid. Power In physics, power is the rate at which energy is transferred or converted. It tells you how quickly energy is used or produced in an electrical circuit.
For a single charge (q) placed in a uniform electric field (E), the potential energy can be given by (U = q \cdot \Delta V), where (\Delta V) is the potential difference between two points. However, for a system of charges, we use the formula derived from the work done in assembling the system of charges from infinity.
