They consist of two conductors separated by an insulator, known as a dielectric. When a voltage is applied to the capacitor terminals, it accumulates opposite charges on the conductors, creating an electric field between them.

- TRUE or FALSE a. A discontinuous change in the voltage requires an infinite current thus a capacitor resists an abrupt change in the voltage across it. b. The inductor takes power from the circuit when storing energy and delivers power to the circuit when returning previously stored energy.arrow_forwardAn (open) electric circuit consists of an inductor, a resistor, and a capacitor. There is an initial charge of 2 coulombs on the capacitor. At the instant the circuit is closed, a current of 3 amperes is present and a voltage of E(t) = 20 cos t is applied. In this circuit the voltage drop across the resistor is 4 times the instantaneous change in the charge, the voltage drop across the capacitor is 10 times the charge, and the voltage drop across the inductor is 2 times the instantaneous change in the current.
