Question

2 multiple choice 3 points a capacitor is: three metal plates facing each other, one having positive, one negative, and one no charge. two metal plates facing each other, each plate having the same charge. two metal plates facing each other, each plate having opposite charges. the electric field between the earth and moon.

Explanation:

A capacitor is a device that stores electrical energy. It consists of two conducting plates (usually metal) separated by an insulating material (dielectric). When a voltage is applied across the plates, one plate accumulates positive charge and the other accumulates negative charge. This is a fundamental property of capacitors. The first option with three plates is incorrect as a basic capacitor has two plates. The last option about the Earth - moon electric field is not related to the definition of a capacitor.

Answer:

Two metal plates facing each other, each plate having opposite charges.
