Giga joule

What are all these numbers and labels and how do they relate to your day-to-day gas and electric usage in your home? Even more basic, how is energy even measured giga joule calculated? In short, it all comes down to the joule.

It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule — In terms of SI base units and in terms of SI derived units with special names , the joule is defined as [ citation needed ]. One joule can also be defined by any of the following: [ citation needed ]. The joule is named after James Prescott Joule. As with every SI unit named for a person, its symbol starts with an upper case letter J , but when written in full, it follows the rules for capitalisation of a common noun ; i.
