In electricity and electronics, a capacitor is a device that stores electrical energy, a passive component. It consists of a pair of conductive surfaces positioned to influence each other totally (that is, all electric field lines that start from one go to the other).

Following a difference

Force (F) is any action that modifies the state of rest or motion of a body. It is measured in Newtons (N). A moment of a force (M) is the product of the value of the force by the distance between that point and the point of application of the force.
