Concept explainers

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.

Question

a) The terminal voltage (bus-bar voltage).

b) The current supplied by each generator c) Total load power.

d) The terminal voltage, if G2 is switched OFF due to maintenance.
