Hello,

As I understand it, the unit of measurement called the Joule is based on a Watt per second. One Joule is 1 Watt per second.

over a 5 second period would you multiply your Watt answer by 5, is that correct?

I'm trying to find a fault and the manufacturer says the power output is 1.76 Joules, but the circuit operates for 5 second periods?

What I don't know is when the numbers are given like that, is that 1.76 joules based on a one second measurement or a 5 second measurement?

eg; 1.76 Joules x 5 seconds = 8.8Joules.

I wonder how many joules my car has and also an Atlas rocket engine,and a human heart?
