FAQs on Why do We Called Transformer a Static Device? Video Lecture - Electrical Machines for Electrical Engg. - Electrical Engineering (EE)
| 1. Why is a transformer called a static device? |  |
Ans. A transformer is called a static device because it does not have any moving parts. It operates based on the principles of electromagnetic induction, where the electrical energy is transferred from one circuit to another without any mechanical motion involved.
| 2. How does a transformer work? | |
Ans. A transformer works based on the principle of electromagnetic induction. It consists of two or more coils of wire, known as windings, which are placed close to each other. When an alternating current (AC) passes through the primary winding, it generates a magnetic field. This magnetic field then induces a voltage in the secondary winding, allowing the transfer of electrical energy from one circuit to another.
| 3. What are the main components of a transformer? | |
Ans. The main components of a transformer are the primary winding, secondary winding, and a laminated iron core. The primary winding is connected to the input voltage source, while the secondary winding is connected to the output load. The laminated iron core provides a path for the magnetic flux generated by the windings, enhancing the efficiency of the transformer.
| 4. What are the types of transformers? | |
Ans. There are several types of transformers, including power transformers, distribution transformers, autotransformers, isolation transformers, and instrument transformers. Power transformers are used in high-voltage transmission systems, while distribution transformers are used to supply power to residential and small commercial areas. Autotransformers provide variable voltage output, isolation transformers provide electrical isolation between circuits, and instrument transformers are used for measuring current and voltage.
| 5. What are the applications of transformers? | |
Ans. Transformers have various applications in electrical engineering. They are used in power transmission and distribution systems to step up or step down voltages. Transformers are also used in electronic devices such as computers, televisions, and audio equipment to provide the required voltage levels. Additionally, transformers are used in industrial settings to regulate voltage and provide isolation between different electrical circuits.
