A long time after the switch is closed, the voltage across the capacitor in terms of the supply voltage is zero.

<h3>What is a Capacitor?</h3>

In an electric field, a capacitor is a device that stores electrical energy. It has two terminals and is a passive electrical component.

Capacitance refers to a capacitor's effect. While there is some capacitance between any two nearby electrical wires in a circuit, a capacitor is a component made to increase capacitance. The term "condenser" or "condensator" originally applied to the capacitor. Condenser microphones, sometimes known as capacitor microphones, are a remarkable exception to the general lack of usage of this name and its cognates in English.

Practical capacitors come in a wide variety of physical shapes and constructions, and there are numerous varieties that are used often. The majority of capacitors have two or more electrical conductors, frequently in the form of metallic plates or surfaces, spaced between by an insulating material. A conductor can be an electrolyte, thin film, metal bead that has been sintered, or foil. The capacitor's charge capacity is increased by the nonconducting dielectric. Glass, ceramic, plastic film, paper, mica, air, and oxide layers are a few examples of materials that are frequently employed as dielectrics. Many typical electrical gadgets use capacitors in their electrical circuits.

A porcupine eats 3,000 J of plant material. Of this, 2,100 J is indigestible and is eliminated as feces, 800 J are used in cellu

Aloiza [94]

Answer:

Explanation:

The total energy ingested is 3000J and of those 3000J, 100J are used for growth and reproduction, this is the part of production in the porcupine, since the other 800J and 2100J are used for internal processes of the porcupine.

Therefore the production efficiency is 100J of the 3000J, let's find out how much it is in percentage:

$\frac{100}{3000}=0.033$
