How do joules relate to volts

Joules To Volts. Enter energy in joules:. Enter charge in coulombs:. Voltage result in volts:. Home Electrical. Formula to convert from Joules to Volts: How to convert from Joules to Volts in 1 single step: Examples of joule to volt conversions: Table of Joules to Volts for conversion, equivalence, transformation Coulomb: 10 :. How many Joules are:. Equivalence in Volts:. However the mains bulb runs on V and also has a current of 1 A flowing through it.

It gives out a lot more energy and so is much brighter. The amount of electricity passing through each bulb per second the current is the same, but the electric charges passing through one bulb have more energy than those passing through the other one.

In other words if the potential difference between two points is 12 V then every coulomb of electricity passing from one point to the other loses 12 J of energy. If we think about the input of energy, then a V supply will give each coulomb J of energy while a 5 V supply only gives each coulomb 5 J.
