Introduction to Voltage
Voltage, also known as potential difference or potential difference, is a physical quantity that measures the energy difference of a unit charge in an electrostatic field due to different potentials. Its magnitude is equal to the work done by the unit positive charge to move from point A to point B due to the force of the electric field. The direction of the voltage is defined as the direction from high potential to low potential. The following two are well-known voltages.
