Hello,
I'm bit confused about relation of the two, would be really great if someone explained it.
So the coulumb is said to be the force between two charges(repelling or attracting), which depends
on quantity of charges and their distance.
Joule is said to be force that is needed to move object of 1kg by 1 metre in second
So, electric current , for example, 1 Ampere, is when 1 Coulumb travels from point A to point B in 1 second, which is coulumbs per second (C/s)
One Volt, is how many Joules one Coulumb transfers(J/C). Here I don't understand
how exactly force between charges transfers energy needed for work ?
And last thing is resistance in electricity - By Ohms law R= V/I,
in other terms that is
````J
```---
````C
-----------
````C
```---
````S
and that equals to J*S ( I tried using math symbols but the code is messing it up)
So basically resistance in electric circuit is how much joules it does not let thru every second?
I'm confused.
