Mark as favorite Copy Link all independent current sources are short circuited and independent voltage sources are open circuited all independent voltage sources are open circuited and all independent current sources are short circuited all independent voltage and current sources are short circuited all independent voltage sources are short circuited and all independent current sources are open circuited Check Answer
ln 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? Mark as favorite Copy Link Thevenin's theorem Norton's theorem Superposition theorem None of the above Check Answer
