Demountable Transformer Model

Transformers are electrical devices that can change the voltage of an alternating current (AC) while keeping the frequency of the current the same. They are important because they allow us to step up or step down the voltage of electricity, which is essential for the transmission and distribution of power.

Let’s understand it with an example. Imagine you have a toy train set that runs on a 12-volt battery. Now, you want to power the same train set using the regular 220-volt power outlet in your home. This is where a transformer comes into play. You can use a transformer to step down the voltage from 220 volts to 12 volts, making it safe for your train set to operate.

In another scenario, when electricity is generated at power plants, it is at a very high voltage. This high-voltage electricity is not suitable for household use. So, transformers are used to step down the high voltage to a lower, safer voltage for use in homes, schools, and businesses. This process reduces energy losses and makes electrical power distribution more efficient.

Demonstration Transformer Working Model consist of two coils of wire, known as the primary and secondary coils, wrapped around a core, usually made of iron. The primary coil is connected to the source of electrical power, while the secondary coil is connected to the load that uses the electrical power. By varying the number of turns in the primary and secondary coils, transformers can step up or step down the voltage.

In summary, transformers play a crucial role in ensuring that electricity can be transmitted efficiently from power plants to our homes and businesses, making it safer and more usable.
