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 core. When alternating current (AC) flows through the primary winding, it creates a varying magnetic field around the core.
This varying magnetic field induces a voltage in the secondary winding, which can then be used to power electrical devices. The ratio of the number of turns in the primary winding to the number of turns in the secondary winding determines whether the transformer steps up (increases) or steps down (decreases) the voltage.
What is the operating principle of a transformer?
The function of a transformer is to adjust the voltage of alternating current to suit different applications.
It can either increase voltage (step-up transformer) for efficient transmission over long distances or decrease voltage (step-down transformer) for safe distribution and use in homes and businesses. Transformers are essential for the efficient transmission of electrical energy from production sites to end users, as well as providing the correct voltage levels for various electrical devices.
What is the function of the transformer?
A transformer operates by exploiting the principle of electromagnetic induction.
When an alternating current flows through the primary winding, it generates a time-varying magnetic field in the core. This magnetic field induces a voltage in the secondary winding due to mutual induction between the two coils. The voltage induced in the secondary winding is proportional to the turns ratio of the windings, which means that the transformer can increase or decrease the voltage depending on this ratio.
A transformer only works with alternating current because the principle of electromagnetic induction requires a changing magnetic field to induce a voltage.
Direct current (DC) produces a constant magnetic field once stabilized, which does not induce voltage in the secondary winding. Without the alternating nature of AC current, the transformer cannot operate because there would be no varying magnetic field to induce a voltage in the secondary coil.
We believe this explanation of What is the operating principle of a transformer? was straightforward.
