Current and charge formula
WebElectric current is nothing but the rate of change of electric charge through a circuit. This current is related to the voltage and resistance of a circuit. It can be represented by I … WebFrom Equation. (1), we may derive the following definition. Capacitance is the ratio of the charge on one plate of a capacitor to the voltage difference between the two plates, measured in farads (F). Note from Equation. (1) that 1 farad = 1 coulomb/volt.
