**transformer**

**frequency**is a type of frequency. Which is equal to both coils of the transformer. Some aspects of transformer frequency are highlighted.

## What is frequency?

**Frequency calculation**

f = Frequency

N = Number of cycles

T = Time

`f=\frac NT`

*In other words,*

*The number of cycles made per second by an alternating quantity is called frequency. It is measured in cycle per second (c/s) or hertz ( Hz ) and is denoted by ( f ).*

**Transformer increase frequency**

**Transformer emf equation**, we get

E = Voltage

F = Frequency

N = Number of turns

`\varphi_m` = Mutual flux

`E=4.44\varphi_mfN` -------( 1 )

The frequency calculation formula for frequency calculation is from the above equation.

`f=\frac E{4.44\varphi_mN}` ----- ( 2 )

*In this case, the frequency equation implies that the flux decreases as the frequency increases.*

The following formula can be used as the winding inductor of the transformer.

L = Inductor

I = Current

`\varphi` = Flux

`L=\frac{N\varphi}I` ----- ( 3 )

*This equation shows that as the flux decreases, the inductor decreases but at the same time the current increases.*

*More is known from Equation 2*

`f=\frac E{4.44\varphi_mN}`

E = Voltage

F = Frequency

N = Number of turns

A = Area

`B_m` = Mutual flux

`f=\frac E{4.44B_mAN}`

`(\varphi_m=B_mA)` `\varphi_m` Instead `B_mA` Has been written.

By doing this, it is understood that as the frequency (f) increases, the area (A) decreases. This area is the winding area of the transformer.

High-frequency transformers tend to be smaller in size than folk frequency transformers. But the power rating remains the same.

Suppose the high-frequency transformer between two 25KVA transformers will be smaller in size than the greed frequency transformer.

Hysteresis loss will increase with increasing frequency in high-frequency transformers.

**Why is the frequency is same in both coils of a transformer?**

When a coal AC is applied to a transformer to produce a magnetic field, the AC voltage of the other coil is absorbed. Connecting an AC source to anyone's coil creates a variable magnetic field in the coil. According to Faraday's formula, voltage is induced in the coil Since the voltage is generated in the secondary with the same supply, the frequency of both the coils of the transformer remains the same.
