Answer 2

I know I have to somewhat use the formula:

power= current x voltage

but I'm not sure if I have to use that one ^

or the

current = power / voltage

Any help would be most appreciated!

Answer 3

tbh i have no clue maybe u should ask dan if he's on....

Answer 9

Hmm, are we assuming a normal supply voltage of 230V?

Answer 10

Yes, I believe so.

Answer 11

Because if that is the case we have a rather simple problem here.

We want to know how much the current can handle

\[\large \text{Current} = \frac{100}{230} = .23\] which would equate to a 3A fuse

(we want to solve for current since we want to know what fuse (in amps) is to be used

Answer 12

Oh right, I see, now! ;O
Thank you ever so much for your help!!! :O
