Voltage is the rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in Volts. Voltage is often described as the difference in charge between two points.

  1. DC Source
  2. AC Source

Electrons Flow


Types of Voltages

Greater the voltage, greater the flow of conducting or semi-conducting medium for a given resistance to flow. Voltage is symbolized by uppercase italic letter V or E

The standard unit is the volt, symbolized by non-italic uppercase letter V

1V will drive 1 coulomb(6.24x108) charge carriers, such as electrons, through a resistance of 1Ω in 1 second.
