If the voltage was 50v and the resistance was 0.5 ohms what would the answer be?

a) 5KW
b) 50KW
c) 0.05KW
d) 500W

Ive been putting down an answer on on online test practise thing that I have and I think its telling me an incorrect right answer!?!?!?!?!?

also, can someone confirm the correct formulae for Power Dissipation? I think that it has that wrong too!:eek::confused:

Cheers,
Mike.
