What is difference b/capacitor and capacitance

A capacitor is a system of two conductors separated by an insulator.

• The total charge of a capacitor is zero while the conductors have charge Q and –Q.
• A single conductor can be considered as capacitor with other conductor at infinity.
• Electric field in the region between the conductors is proportional to the charge Q.
• Capacitanceis denoted by, C = Q/V. It depends on:
  • Geometrical configuration (shape, size, separation) of the system of two conductors.
  • Nature of insulator/dielectric separating
• Charge on the capacitor leaks away due to reduction in the insulating power of the intervening medium. This happens due to higher potential difference causing strong electric fields.
• Maximum electric field which a dielectric medium can withstand without breakdown and prevent leaking of charge is called dielectric strength. Air dielectric strength is 3 x 106 Vm-1.
• SI unit of capacitance is F (Farad).

The capacitor is nothing but an electronic device used for storing charge. Capacitors are very common components in electronic circuits. Different types of capacitor are available in the market which works essentially in the same way. The perspective of a capacitor is a couple of metal plates isolated by a gap in which there is an insulating material called as the dielectric.

Electrolytic, Micro Electro-Mechanical Systems (MEMs), Tantalum and Supercapacitors are the different types of capacitors available in the market. Capacitors can charge and discharge their storage charge rapidly permitting them to work from numerous points of view. They have imperative spots in everything from voltage balancing out circuits in delicate gadgets to changing over AC energy to DC to charge batteries in everything.

The capacitance is defined as the ratio of charge store per unit voltage. <i>C=Q/V</i>

Where C is the capacitance of conductor

Q is the amount of charge gained

V is the potential gained.

The capacitance of a parallel plate capacitor is given by <i>C</i>=εr<i>A</i>/<i>d</i>

The property of capacitance that restricts an adjustment in voltage is misused with the end goal of leading signs with a higher recurrence part while anticipating signs of lower recurrence segments from passing.
