How does the transformer lower the voltage?
A transformer lowers voltage through a process called electromagnetic induction. It consists of two coils of wire, called the primary and secondary coils, wound around a magnetic core. When alternating current (AC) flows through the primary coil, it creates a magnetic field which induces a current in the secondary coil.
In a step-down transformer, the secondary coil has fewer turns of wire than the primary coil, resulting in a lower output voltage than the input voltage.
How do transformers step down voltage?
A voltage transformer works by transferring electrical energy between two or more circuits by electromagnetic induction.
It is based on the principle that a varying magnetic field created by current in the primary coil induces a voltage in the secondary coil. The voltage induced in the secondary coil depends on the ratio between the number of turns of the primary coil and the number of turns of the secondary coil. This ratio determines whether the transformer increases or decreases the voltage.
Transformers are used to change the voltage of alternating current by increasing (increasing) or decreasing (decreasing) the voltage level. This is achieved by the turns ratio between the primary and secondary coils.
For example, in power distribution, a step-up transformer increases voltage for efficient transmission over long distances, while a step-down transformer reduces voltage to safer levels for use in homes and businesses.
How to decrease the voltage of a transformer?
The part that transforms energy from low to high voltage in a transformer is the primary coil, which is connected to the input voltage source.
The secondary coil, with more turns of wire than the primary coil, induces a higher voltage due to electromagnetic induction. This configuration is used in step-up transformers to increase the voltage from the primary side to the secondary side.
To transform high voltage to low voltage, a step-down transformer is used. This transformer has a primary coil with more turns of wire and a secondary coil with fewer turns. When an alternating current flows through the primary coil, it induces a lower voltage in the secondary coil.
The voltage reduction is proportional to the turns ratio between the two coils.
This process is widely used in electrical distribution systems to lower high transmission voltages to levels suitable for consumer use.
