Question 84. This mention statement is associated with “Any number of current sources in parallel may be replaced by a single current source whose current is the algebraic sum of individual currents and source resistance is the parallel combination of individual source resistances”.

Question 86. “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

Question 87. For high efficiency of transfer of power, internal resistance of the source should be

Question 88. “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

Question 89. “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
