To find the exact output of an AC generator is a daunting task. This output is produced as a result when all the parts of the generator work in harmony.

This requires the generator’s parts to work together to produce a uniform flow of current. The failure of one component can put all the machinery to a halt. Despite several minimal losses of an AC generator, need that the output be optimal.

First, we need to understand what the output of an AC generator is and how it creat.

## What is the output of an AC generator?

Simply put, the input is the amount of effort you put into something. The output is what comes out as a result. The AC generator’s creation is the amount of current produced by the generator when all its parts work.

With its name, we can deduce that the output will be an Alternating one.

## How to show the graphed output?

In the below figure, the coil imagine to be moving in a clockwise manner. , the magnetic field points from left to right. Also, it shows five different positions of the wave in the magnetic field.

Also,

Now to understand the production, the output-current show in a graph.

- The independent quantity is shown on the X-axis, i.e., Time in seconds (s).

- The dependent quantity is on the graph’s Y-axis, i.e., induced current in Amperes (A).

A: The alphabet A denotes the resting position of the coil, which is the 0o. Here the Magnetic field and the plane of the ring both are perpendicular to each other. The implication is that the loop and the magnetic field lines are parallel to each other.

Due to the parallel position in the graph’s A point, no magnetic flux is getting produced. Hence the value zero.

B: The alphabet B denotes the coil’s position at 900 to the filed lines. Due to this, the maximum magnetic flux is being created. Hence maximum induced current.

C: The alphabet C denotes the resting position of 1800 but in a completely opposite direction. This results in the same result as position A of the coil. Hence no current induce, and the value is zero.

D: The alphabet D denotes the coil at 2700, which is the same as 900, but in the opposite direction. Hence the induced current is most extensive but in the opposite direction to what was at B.

E: The alphabet E represents the coil position at 3600. This means that, at this point, the coil has returned to its original place of 00 after a complete rotation. So no current induce hence the value 0 in the graph.

## How to increase the output?

The output of the AC generator can increase in the following manner:

- Increasing the magnetic field strength. This can do by decreasing the distance between the magnet and the coil.
- Using a stronger magnet. This will result in the production of a dense magnetic field.
- Increasing the number of turns in the coil. The increment will increase the induced current.
- Keeping the coil fixed and rotating the magnetic field around it. This reverses the held practice and results in more induced current than generally.
- Increasing the frequency of the coil.

To increase the frequency of the coil, let’s understand the concept of frequency.

## What is the frequency, and How to calculate it?

To find the frequency of an AC generator, first, we need to know the concept of the period.

The period is the Time taken by a complete cycle of the wave to pass a point.

In the case of AC generators, the period is the Time taken by the coil to finish its complete cycle. The completion of the process results in the formation of a whole wave from A to E.

Now, frequency is the number of the complete cycle of waves passing through a point in a unit of Time (Linson, 2015). So the frequency of the AC generator is the inverse of the period.

Mathematically,

The frequency of the coil can increase by reducing the period to a half. This results in a doubling of the frequency.

**f = 1/ (1/2) T**

**f = 2/T**** **

**f = 2(f’)**

## What is the difference between a generator’s load and the output?

The amount of power that is being consumed from the generator call the load. While the output is the amount of current produced by the generator. N a typical household, the operating units like lights, heating, AC units, televisions, etc., are loads.

In a nutshell, the total sum of all the power requirements call a load. This load needs fulfill by the AC generator. When it fails to do so, the methods described above apply to increase the output and load.

As every generator has its own construction process, so each one acts.

## What is the difference between kW and kVA, And How to convert?

The power ratings express with the units such as *Watts and Kilowatts, Amperes, Volts, etc.*

The generator engine reacts based on the amount of ‘active power’ available to it—the active power available measures in kilowatts (kW).

The amount of current drawn from the AC generator gives its power factor. This measure in kilo-Volt-Ampere (kVA). It is also called ‘clear power.’

If the generator’s ideal efficiency consider, then kW and kVA will be equal (Philip, 2018). As no generator works on a perfect level, the kW and kVA are always unequal.

Convert kW to kVA, the generator’s efficiency or power factor (pf) need. This ranges from zero to one. On an average scale, the efficiency of a generator is almost 0.8.

The formula or the interconversion is

**kW / pf = kVA**

In the case of industrial places, kW use to describe the power of the generator. But in household places and in some countries, kVA use. While both can tell the power of the generator, the power factor still plays a central role.

The average considered efficiency value of 0.8 shows that the kVA value will always be higher than the kW value. The equation for average AC generators can writ as:

**kW = (0.8) kVA**

It is always better to have a good idea of the load requirements and the apparent load provided by the generator. This helps in the calculation of the overall output needs that your generator can fulfill.

## Conclusion:

We conclude that the output is an essential factor that should consider. In comparison, buying a new AC generator. Likewise, the work can increase by following recommendations without changing the machinery. Comment below if you have any queries about the article.
