Back to the OP.

In my day you would have got 5 points for calcualtinbg what raing of
fuse was theretically required and a further 5 for pointing out that
this was in fact irrelevant, as the purpose of the fuse was not to
protect the appliance, but its cable and therefore 13A would be a
standard fitting.

That would surely depend on whoever marking it had access to the regs
governing such things and understood them. Not something you could
guarantee.

But, of course, if they don't understand a subject they should not be
setting examination questions on it. Even if the question is merely
designed to beautify Ohm's law and power calculations.

Not really. OK to set a theoretical question which doesn't take into
account practice. IIRC, the reason not to have a vast range of plug top
fuses these days is that most punters simply don't understand such things
and will just fit what is to hand - usually the most common one, ie 13
amp.

The original question didn't state is was dealing with a fused plug anyway.
