A delta circuit has each element of value $$\frac{{\text{R}}}{2}.$$ The equivalent elements of star circuit with be

“Maximum power output is obtained from a network when the load resistance is equal to the output resistance of the network as seen terminals of the load”. The above statement is associated with

“In any linear bilateral network, if a source of e.m.f. E in any branch produces a current I in any other branch, then same e.m.f. acting in the second branch would produce the same current / in the first branch”. The above statement is associated with

“In any network containing more than one sources of e.m.f. the current in any branch is the algebraic sum of a number of individual fictitious currents (the number being equal to the number of sources of e.m.f.), each of which is due to separate action of each source of e.m.f., taken in order, when the remaining sources of e.m.f. are replaced by conductors, the resistances of which are equal to the internal resistances of the respective sources”.
The above statement is associated with
