1A fuse in a 13A plug - what will happen?

[Discharged]

I'm trying to explain to my kid (8) why were have fuses in plugs, and he found a 1A glass fuse lying 'round and he asked me if we could put that into a 13A plug. I said 'no' it would blow if you plugged into the mains.

Then I wondered if that really would happen... So thought I'd better ask here for clarification.

What does happen if you put a too-lower rated a fuse into a plug? To my mind, what happens depends on the appliance being supplied - what current it draws.

Any idea on this, please?

well i could nit pick here n all and say you are both wrong as its 24.7mm actually.....splitting atoms guys..lol...rrr:

That may be the case in Yorkshire bonny lad, but here in Geordieland it's 25.4

this is ohm law P = I x V
The appliance is 800watts divided by 230 = 3.5 Amps
put a 1 amp fuse in plug it will go bang

P = I x V is not ohms law, its the formula we derive from ohms law,... just saying ;-)
