Norton’s Theorem Formula
From our previous derivations, we can write down the formula as
VTh= R2/(R1+R2). V
and RTh= R3+ (R1 .R2)/(R1+R2)
Now, we can calculate the short circuit current as
ISC= VTh/ RTh
When Norton’s theorem is applied to any general circuit, the current source is in parallel with resistance and we can write the current across the load as
IL= IN. RN/(RN+RL)
Norton’s Theorem
Electrical engineering widely uses different theorems and laws to simplify the circuits involved in this field. One such theorem is known as Norton’s Theorem which is used for analysing linear circuits in electrical engineering. In this article, we will study what is Norton’s Theorem, what is the statement of this theorem, and what the circuit implementation of this theorem looks like. We will also study the step-by-step Procedure for applying Norton’s theorem to our circuit and see how it can determine IN or ISC.
Once we have successfully discussed the advantages and applications of this theorem, we will proceed to see the limitations of this theorem. Some solved examples have been solved for a better understanding of the theorem. The article concludes with some frequently asked questions that readers can refer to.
