Capacitors
Capacitors store and release electrical energy. They are commonly used for decoupling, filtering, and energy storage in electronic circuits.
- It is used to pass AC and block DC.
- It opposes the flow of direct current.
- It consists of two conducting parallel plates separated by dielectric.
- Dielectric is made up of ceramic, mica, glass, waxed paper, and bakelite.
Capacitor current equation with respect to time:
[Tex]I(t) = C \frac{dV(t)}{dt} [/Tex]
- I(t) stands for current in capacitor with respect to time
- C stands for capacitance
- V(t) stand for voltage across the capacitor with respect to time t.
Advantages of Capacitor
- It stores electrical energy in it.
- It is used in timing circuits.
- It is used to stabilize voltage in circuit.
Disadvantages of Capacitor
- it stores limited energy only.
- It may leak its charge over time.
Applications of Capacitor
There are many applications of linear components like capacitors which include:
- It is used for storage of energy.
- It is used in filter circuits to minimize the repel voltage.
- It is used in tunning circuits for selection of frequency.
- It is used in timing circuits to select the time.
- It is used in Amplifiers.
V-I Characteristics of Capacitor
- V-I Characteristics of a capacitor can be explained by the relation between the applied voltages and the current flowing through it
- From Ohm’s law, we know that when the voltage applied across the resistor increases, the current flowing through it also increases i.e. the voltage applied is directly proportional to current.
Linear Components – Electrical Circuits
In electrical circuits, some electronic devices follow a linear relationship between input and output, called Linear Components. These components follow the law of superposition principle and homogeneity. In this article, we will learn about the role of Linear components in Electrical Circuits, their properties, types, working, advantages, disadvantages, and applications of Linear components.
