- 10. TYPES OF CAPACITOR Differentcapacitor types are used based on voltage requirement, capacitance, and other properties.A capacitor is formerly termed as a condenser. Every capacitor consists of plates or two electrical conductors and is separated by a dielectric.They are employed in electrical circuits found in various electronic devices
- 11. TYPES OF CAPCITOR Thecapacitors can be classified into two types: Polarized Unpolarized

- 13. UNPOLARIZED CAPACITORS Unpolarized capacitorsare preferred over polarized capacitors because it doesn’t get destroyed by reverse voltage and can be used in pure AC circuits.They also find applications in DC circuits as they don’t have positive and negative ends.The frequency of the unpolarized capacitor is high and the leakage current is low.
- 14. Capacitors are mainlydivided into two mechanical groups: • Fixed capacitors • Variable capacitors
- 15. Various capacitor types Ceramic capacitors Film capacitors Powerfilm capacitors Electrolytic capacitors
- 24. CONSTRUCTION OF CAPACITORS Thebasic construction of all capacitors is similar. The construction of capacitor is very simple. A capacitor is made of two electrically conductive plates placed close to each other, but they do not touch each other. These conductive plates are normally made of materials such as aluminum, brass, or copper.
- 25. CONSTRUCTION OF CAPACITORS Theconductive plates of a capacitor is separated by a small distance. The empty space between these plates is filled with a non- conductive material or electric insulator or dielectric region. The non- conductive material or region between the two plates may be an air, vacuum, glass, liquid, or solid.This non-conductive material is called dielectric
- 27. CONSTRUCTION OF CAPACITORS Thetwo conductive plates of the capacitor are good conductors of electricity. Therefore, they can easily pass the electric current through them. The conductive plates of the capacitor also hold the electric charge. In capacitors, these plates are mainly used to hold or store the electric charge.
- 28. CONSTRUCTION OF CAPACITORS Adielectric material or medium is the poor conductor of electricity. They cannot pass electric current through them. In capacitors, the dielectric medium or material block the flow of charge carriers (especially electrons) between the conductive plates. As a result, the electric charges that try to move from one plate to another plate will be trapped within the plate because of the strong resistance from the dielectric.
- 29. CONSTRUCTION OF CAPACITOR Dielectricmaterial does not allow the flow of charge carriers, but they allow the electric force, electric charge, or electric field produced by the charged particles (electrons). As a result, when charge is build up on the two plates, a strong electric field is generated between the two plates
- 30. HOW CAPACITORWORKS? Capacitor with novoltage source • When no voltage is applied to the capacitor, the total number of electrons and protons in the left plate of the capacitor are equal. • We know that any object, which has equal number of electrons and protons is said to be electrically neutral.
- 31. HOW CAPACITORWORKS? ❑ Hence,the total charge of the left plate cancels out and becomes electrically neutral. Therefore, the left plate of the capacitor is said to be electrical neutral.
- 32. On the otherhand, the right plate also has equal number of electrons and protons. Therefore, the total charge of the right plate cancels out and becomes electrically neutral No electric charge means no electric field.Therefore, the capacitor does not store charge when no voltage is applied
- 33. CAPACITOR CIRCUIT SYMBOL Thecircuit symbol of a basic capacitor is shown in the below figure.The capacitor symbol is represented by drawing two parallel lines close to each other, but not touching. It consists of two terminals.These terminals are used to connect in the circuit.
- 38. RESISTANCE Resistance is ameasure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance. He is credited for formulating Ohm's Law.
