The teacher said that The farad is the measure of capacitance in a circuit & has the unit of distance is True?

Answer 1

The farad is the unit assigned to the measure of capacitance in a capacitor (ie a capacitor has a capacitance of 1 farad).

A farad is defined as being coulombs per volt, so that in the 1 farad capacitor, 1 coulomb of charge will move from one plate of the capacitor to the other for every volt of potential difference (aka voltage) between the two plates.

This article sort of helps to illustrate the idea better:
