Norton's theorem example
Answers
Answer:
We know that, if the load changes, then the calculation of various parameters of electric circuits is difficult. So, network theorems are used for calculating the network parameters easily.
In this Norton’s theorem also we follow the procedure similar to thevenins theorem (up to some extent). Here, primarily remove the load (consider resistor R2=2 Ohms as load in the circuit) as shown in the above figure. Then, short circuit the load terminals with a wire (exactly opposite to the procedure that we follow in thevenins theorem, i.e., open circuit of load terminals) as shown in the below figure. Now, calculate the resultant current (current through resistors R1, R3, and short circuit line after removing R2).
The Nortons source current is equal to 14A which is used in the Norton’s equivalent circuit as shown in the below figure. Norton’s theorem equivalent circuit consists of the Norton current source (INorton) in parallel with Norton’s equivalent resistance (RNorton) and load (here R2=2Ohms).
To see all the picture from the above of the answer right to left .
