R = VI

Resistance (Ohms) is equal to the potential difference (Volts) multiplied by current (Amps)

Uhhh... no.

V = IR

It simple and I don't see why it needs a 'shortcut'.

I think he means an easy way to remember it. Instead of trying to memorise it, just do some practice problems that use the formula and it should stick into your head.

if your not a mathsy person (but doing physics....ok) and hate to rearrange the equations: draw a triangle like...so (ish)... and put your finget over the given, then just multiply or divide

eg finger over: v = IR
finger over R=V/I


/\
/V\
/I*R\


meh my physics teacher was a fan of it...i think its just over complicating things...
