Volts Definition and 104 Threads

volts, current, Amps?? Please could someone explain to me which are affected by which and what they do? I am a bit confused.

what is the difference between electron volts and proton volts?

I was looking at a http://chemlab.pc.maricopa.edu/periodic/isotopes.html and was wondering why the half-life was sometimes replaced with electron volts? There's an example from the table below: Helium-6 806.7 milliseconds -> Lithium-6 Helium-7 160 KEV -> Helium-6...

current is 5 amperes. voltage is 10 volts. 1. what would be the charge if there is energy of 30 J? 2. what would be the time taken to supply the use of 30J? For 1, is it 30J/ 10V = 3 coulombs For 2, is it 3C/ 5 amperes = 0.60 seconds Anyone can help?
