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.
