It wasn't supposed to be a trick question. The supply has a power

Are you implying that a domestic supply is guaranteed to have a power
factor of 1?

Not so!

The numerical power factor eg 1, 0.9 etc - is a measure of the phase
angle between the LOAD current and the applied voltage. It is also the
measurement of the ratio of real power and apparent power or the ratio
of watts (W) to voltamperes (VA).

....


The power companies worry about the overall power factor of the supply
for obvious reasons.

You have just contradicted yourself.
