Yes, absolutely correct.

Don't you all recall having to remember the word CIVIL at school? (referring to the fact that in a Capacitive C load, the current I leads the voltage V. In an inductive L load the voltage V leads the current I). Measure time difference between both (zero cross is easiest), simple math determines the rest.
