Joule

Here you can convert energy units Joule value into any other energy units.

A joule is a unit of energy in the International System of Units (SI) and named after the British physicist James Prescott Joule.

The symbol for joule is J.

A joule is equal to the work done when a current of 1 ampere is passed through a resistance of 1 ohm for 1 second.

Q = I2× R × t

  • Q = the amount of heat – the Joules (J)
  • I = current intensity
  • R = electrical resistance (Ω)
  • t = time in which the current flows expressed in seconds

Joule And Force

A joule definiton says that it is an energy trasferred to an object when we work with a force of 1 Newton on that object in the direction of its motion for 1m of distance.

This would give us a formula:

W = F x d

  • W – Energy (J)
  • F = force (N)
  • d = distance (m)
