I'd like to understand a bit more about what actually gives you an electric shock. I think the more you understand something the safer you will be.
I have been taught that it is the current (amps) that gives you the shock, but this then confuses me with regard 12v equipment (lets say anything domestic - downlights for example using a transformer), as if the lights are 10W then:
Power = Voltage x Amps
10 = 12 x Amps
Amps = 10/12 = 0.83
If however the light were from the mains:
Amps = 10/230 = 0.04
So according to the maths a low voltage system uses more current and would be more dangerous as its amps that cause the shock. I know I'm missing something simple as this cant be right but I get a bit carried away with maths!
Could anyone explain this a little please?
