What is the operating principle of a transformer?
The operating principle of a transformer is based on electromagnetic induction. It consists of two coils of wire, called the primary and secondary windings, wound around a common magnetic core. When alternating current (AC) flows through the primary winding, it creates a magnetic field that induces a voltage in the secondary winding through the core. The ratio between the number of turns of the primary winding and that of the secondary winding determines the voltage variation between the two windings.
What is the operating principle of a transformer?
The function of a transformer is to change the voltage level of an alternating current (AC) electrical signal. It can increase (increase) or decrease (decrease) the voltage depending on the winding ratio. This ability to adjust voltage levels is crucial for efficiently transmitting electrical energy over long distances and providing appropriate voltage levels for various electrical devices and systems.
What is the function of the transformer?
A transformer works by transferring electrical energy from one circuit to another through electromagnetic induction. The primary winding receives the input voltage, creating a magnetic field in the core. This magnetic field induces a voltage in the secondary winding, which can be higher or lower than the primary voltage depending on the winding ratio. This process allows the transformer to adjust voltage levels as needed.
A transformer is used for a variety of purposes, including voltage regulation in power transmission and distribution systems, insulation between electrical circuits, and impedance matching. In power transmission, transformers step up the voltage for efficient long-distance transmission, then step it down for safe use in homes and businesses. They also provide electrical insulation to protect sensitive equipment and ensure compatibility between different electrical systems.
In a power plant, a transformer plays a vital role in increasing the voltage generated by the plant’s generators to a higher level suitable for transmission over long distances. This high-voltage transmission minimizes energy losses due to the resistance of power lines. At the receiving end, another transformer steps down the voltage to a safe, usable level for distribution to consumers and industrial users.
