Joule and Watt Units Relation

07/23/2012 12:58 PM

If : 1J = 1A x 1Ohm x 1sec

and : W = J/sec

Then : W= A x Ohm x sec / sec = A x Ohm ?

The joule is a unit of work and energy. It is equal to a newton-meter (N-m). Note that the unit of torque is also the newton-meter, but scientists don't use the word joule when they are talking about torque.The watt is a unit of power and is defined as a joule per second, so you can see that power is work per unit time.One joule is equal to one watt-second.

So you're comparing apples and oranges, one is a unit of power, one is a unit of energy...like saying how much horsepower is your gas?

If : 1J = 1A x 1Ohm x 1sec

J = A2 x R x Sec = WxSec

and : W = J/sec

W = J/Sec

Then : W= A x Ohm x sec / sec = A x Ohm ?

Then W = A2 x R x Sec /sec = A2 x R
