Working Principle of Transformers
A transformer works based on Mutual Inductance. This is the result of Faraday’s Law of Electromagnetic Induction. Which states that when the amount of magnetic field passing through a coil changes, it makes electricity flow in the coil. A transformer usually has two coils (called primary and secondary) wrapped around a core.
The core is made of stacked sheets of metal. These coils are connected through mutual inductance. When electricity flows through the primary coil, it creates a changing magnetic field. According to Faraday’s law, this change in the magnetic field produces electricity in both the primary and secondary coils.
Formula for Transformers
Vp/Vs = Np/Ns
Vp*Ip=Vs*Is
Where,
Vp = Primary voltage
Vs = Secondary voltage
Np = number of turns in the primary
Ns = number of turns in the secondary
Is = Input current on the secondary coil
Ip = Input current on the primary coil
So by changing the number of turns of the coil we can easily regulate the voltage as well as the current flowing through.
Applications of Transformers
Transformers are like silent giants in the world of electricity. They’re used to change the voltage levels, which helps electricity move smoothly through circuits. They’re like guardians, making sure power flows safely and efficiently in our electric-powered world. Whether it’s lighting up our homes or helping with advanced medical tests, transformers are super important in our everyday lives. Let’s explore how these simple but crucial devices work and how they make a big difference in how we use electricity.
