If "Q" and "t" are measured in coulombs and seconds respectively, "I" is in amperes. The electrical charge stored in the capacitor is measured in coulombs. One abcoulomb is equal to ten coulombs. This is done to show that the experiment is approaching an expected number of coulombs. He removed the "shrine" in which the Coulombs had attempted to plant evidence of fraud. Coulombs main assumption is that the failure surface is planar.
