The Transformer is a device used to change voltage into the designated desired voltage to fit an application. Transformer also is one of the most important electrical device widely used in today’s everyday life. An ideal transformer is the one worked with 100% efficiency. However, in reality, a transformer may not achieve 100% efficiency. a) Draw a transformer principle element. b) Explain the working principle of a transformer. c) Identify the parameter that remains unchanged whenever the transformer is in operation and explain why it remains unchanged. d) With the help of a sketch, identify where all the losses happen and their type in a transformer. e) What is the difference between modern and old mobile phone charger,

Maximum power transfer theorem

A resistive load will consume maximum power from a network when the load resistance is equal to the resistance of the network as viewed from the open-circuit terminals, with all energy sources removed leaving only the internal resistances. Physicist Moritz von Jacobi introduced the maximum power transfer theorem in 1940. Therefore, this theorem is also known as Jacobi's law.
