Voltage



Symbol: V

Unit: Volt
 Symbol for Volt: V


Voltage (potential difference) is the difference in the amount of electrical energy between two points in a circuit.
Examples:
  • Voltage = 5 volts
  • V = 5 V

Slide 3 - Diapositive

Another definition of voltage 
Energy is measured in joules J. The number of joules that each coloumb ( batch of electrons) gives to a component is known as volt. 1 V = 1 J/C
