Learn MoreWhat is a Capacitor? Definition, Uses & Formulas
Learn MoreA capacitor is a device that is designed to exhibit a specified capacitance. We can now make the connection to the concept of the capacitor as it appears in elementary circuit theory. In circuit theory, the behavior of devices is characterized in terms of terminal voltage (V_T) in response to terminal current (I_T), and vice versa.
