Explain transformer construction with suitable diagram.
A transformer is an electrical device used to change the voltage level in an alternating current (AC) electrical circuit. It operates on the principle of electromagnetic induction, which enables the transfer of electrical energy between two or more circuits through inductively coupled conductors. The main components of a transformer include:
1. Core: The core provides a path for the magnetic flux. It is typically made of laminated sheets of silicon steel to reduce eddy current losses. The core is designed to have low reluctance to magnetic flux, which helps in efficient energy transfer.
2. Primary Coil (Winding): This is the coil through which the input voltage is applied. The current flowing through this coil generates a magnetic field that induces a voltage ________ _______ ___ _________ _______ ____ ____ ____ _________ ________ ____.
