Q1. | "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 |
