Q4: A power distribution station consisting of 100OKVA, 4500V/225V, and 50 cycles per second single-phase core type mutual inductance equipment is to have an approximate electromotive force per turn of 15V and operates witha maximum flux of1.4T. Based on the above scenario justify what will be the values of turns, currents, and cross-sectional area of the core? Analyze the range of load resistance of this equipment. If the load resistances are very high discuss the various methods on its heat reduction process.

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.
