There is definitely a problem with that.

But an instantaneous value of 10 joules/sec; that
is useful.


But that instantaneous instant is NOT one second
long.

A rate of 10 joules/sec is valid at any time in which there is a 10
volt differential and a current flowing at a rate of one coulomb per
second (and a half coulomb in a half second, and a thousandth of
coulomb in a millisecond, and like that).

Exactly how long is that instantaneous
instant? 1 ms? 1 us? 1 ns? more? less?

That is a question more typically asked by someone who has never taken
a calculus class.
