Transformers
A transformer is also a passive electronic component. A transformer is used to transfer electrical power from one circuit to another via magnetic media i.e. magnetic core.
- It has two windings on a core. The winding to which input power is given is called the primary winding.
- The winding which delivers power to the load is the secondary winding.
- When transformers step up or step down voltage, power, and energy remain the same on the primary and secondary sides. As energy is not being amplified.
- Transformers are often used to raise voltage levels and keep the power constant.
Transformer current Equation
[Tex]\frac{I1}{I2} =\frac{N2}{N1} [/Tex]
- I1 stands for primary current in transformer
- I2 stands for primary current in transformer
- N1 stands for number of turns in primary winding
- N2 stands for number of turns in secondary winding
Advantages of Transformer
- It is used in changing the voltage.
- It offers isolation between input and output in circuits.
Disadvantages of Transformer
- It can be heavy
- It is only limited to AC circuits.
Applications of Transformers
- It is used to raise voltage levels.
- It is used in power generation
- It is used in transmission and distribution.
- It is used in lighting, audio systems, and electronic equipment.
V-I characteristics of Transformer
- V-I Characteristics of a Transformer 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.
Other Linear components in electrical circuits include controllers, sensors, diodes, thermistors, varactors, transducers, and many other common components. These components follows ohms law. These components are available as through-hole and components, and many are available in common packages with standard land patterns.
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.
