Simple explanation of voltage please
So I've been teaching myself more about board level repair and never took the time to properly learn basic electrical concepts such as voltage. Just about everything makes clear sense but voltage to me.
I've read about 50 different (what feels like) definitions online, as well as on youtube.
I've read it's the potential electric difference between two points (charges).
Also it's the pressure that controls the current.
From this I'm assuming it's the measurement of the difference in electric charge between two points. This acts as pressure maybe?
Can anyone please give a simple explanation of how voltage is determined and it's purpose in a circuit?
Esta é uma boa pergunta?
