What is the Function of Transformer?
Transformers are essential electrical devices that play a crucial role in the transmission and distribution of electrical energy. By converting AC and adjusting voltage levels, they ensure efficient and safe delivery of power over long distances.
A transformer is an electrical device designed to change the voltage levels of alternating current (AC) in electrical systems. Its primary function is to convert AC from one voltage level to another, either by increasing the voltage (step-up) or decreasing it (step-down). This voltage transformation is achieved through electromagnetic induction, allowing for efficient energy transfer and minimizing losses during transmission.
The primary function of a transformer is to convert AC voltages from one level to another. It can either increase (step-up) or decrease (step-down) the voltage, depending on the specific requirements of the electrical system. This ability to manipulate voltage levels is the cornerstone of efficient power transmission and distribution.
Why Do We Need to Change Voltage Levels in Electrical Systems?
Changing voltage levels in electrical systems is necessary for several reasons:
How Does a Transformer Achieve Voltage Transformation?
A transformer achieves voltage transformation through the principle of electromagnetic induction. The device consists of two coils of wire, known as the primary and secondary coils, wound around a common iron core. When an input voltage is applied to the primary coil, it creates a magnetic field in the iron core. This changing magnetic field induces an output voltage in the secondary coil. The voltage levels are determined by the ratio of the number of turns in the primary coil to the number of turns in the secondary coil. For instance, if the secondary coil has more turns than the primary coil, the voltage is increased, resulting in a step-up transformer. Conversely, if the secondary coil has fewer turns, the voltage is decreased, creating a step-down transformer.
