I know that to work out the wattage It's V times A = W

But what if you want to work out the A, If you only have the V and W

Would it be V % W = A

Or am I wrong

Volts * Amps = Watts
Watts / Volts = Amps
Watts / Amps = Volts

Technically its P = I / V ;) But I won't confuse you, lol.

It would be Watts divided by Volts.
So, if you had a voltage of 12, and an amperage of 1,5, you'd start with the following:
12 x 1.5 = 18
Divite 18 by 12, and you get an Amperage of 1.5.

That's quite a chart, for x * y = a I just remember the triangle,
Code:
   ___
  / A \
/ X | Y \
 --------


You cover the one you want to calculate, so to get A you cover it and you get X*Y, for X you get A/Y etc.
