20b - Norton's Theorem with Solved Examples

Описание: 20b - Norton's Theorem with Solved Examples #knust

In this video we are going to learn how to solve circuit problems using Norton's theorem.
Norton's theorem states that any linear circuit connected between two terminals can be replaced by a Norton's current IN in parallel with a Norton's resistance RN.
To find the current flowing in a resistor;
1. Remove the resistor you want to find the current through and mark the terminal
2. Find the IN using KVL
3. Deactivate all independent sources, open circuit current sources and short circuit voltage sources and find the RN
4. Produce the Norton's equivalent circuit and reconnect the resistor you removed.
5. Find the current through the resistor using the formula I = RN/(RN + RL) * IN
