Ferrites are magnetic materials that are considered better than pure metals because of their wide range of properties, such as low cost, high resistivity, easy manufacturing, and superior magnetization. They are widely used in radar, audio & video, memory cores of computers, microwave devices, and satellite communication. Their high electrical resistance and low eddy current … Read more
Biasing or applying bias means applying a steady dc voltage. Usually, when we apply a voltage across components like resistors, inductors, capacitors, etc. we do not need to consider the polarity of the voltage applied. But in the case of semiconductor devices such as a diode, BJT, FET, etc., the polarity of the voltage is … Read more
Current transformer and Potential transformer are the types of instrument transformer. An instrument transformer is a special type of transformer that is used in the measurement of high voltage and high current, not allowing measuring instruments to come in direct contact with high voltage circuits. Potential transformer is also known as voltage transformer. In this … Read more
A power transformer is one of the types of transformer. The basic function of this transformer is to transfer electrical energy from one voltage level to another voltage level without changing the frequency. These transformers are used at specific locations in power systems. In this article, we will see the basic characteristics of a power … Read more

In other words, a transformer is used in many applications. In this article, we will throw light on the applications of a transformer in detail. Different uses of transformer 1. Change the … Read more
A distribution transformer is one of the types of transformer. They are used only for distribution purposes. These transformers can be easily seen in your localities. The distribution transformers (generally pole mounted) are those installed in the location to provide utilization voltage at the consumer terminals. The secondary of a distribution transformer is connected directly … Read more
A transformer is an important device used for stepping up or stepping down voltage or current without changing the frequency. It is a highly efficient device due to the absence of rotating parts. There are different parts of transformer. In this article, we will see the transformer parts and their functions. Let see each part … Read more
The performance of a transformer can be determined with the help of two important performance indicators i.e. transformer efficiency and transformer voltage regulation. In this article, we will see what is transformer efficiency. We will also derive the condition of maximum efficiency. Transformer Efficiency Definition The efficiency of a transformer is defined as the ratio … Read more
In the applications of power electronics, converters and inverters play a very crucial role. The conversion of AC to DC or DC to AC is always an important phenomenon in the field of power electronics as well as in day-to-day life. In general terms, all the devices that convert power from one form to another … Read more
A proximity sensor is one of the types of sensor. It is able to detect nearby objects without any physical contact. These sensors are commonly used in smartphones and tablets. There are several proximity sensor applications apart from smartphones or tablets. In this article, we will see the different applications of proximity sensors in detail. … Read more
