Which of the following theorems are used to simplify a linear circuit into an equivalent form with a single source and impedance? A. Thevenin's theorem B. Norton's theorem C. Superposition theorem D. Reciprocity theorem
Assertion (A): A network in which circuit elements like resistance, inductance and capacitance cannot be physically separated or analysis purpose is called lumped network. Reason (R): Most of the electric network are lumped in nature.
