Difference between Joules, Coulombs and Volts

Postby Cameron Sasmor 1G » Sat Feb 07, 2015 10:52 am

What is the difference between joules, coulombs, and volts? To me they all seem like units of energy, either in the form of work or electric potential, so I don't understand how volts even exist...

1 coulomb = the amount of electrical charge in 6.24 x 10^18 electrons.
Joules = a measure of energy.
Voltage is the amount of energy (J) per unit charge (C).
1 volt is exactly 1 joule of energy done by 1 coulomb of charge (1J/C).
