18 - Thevenin's Theorem - Concept with Solved Examples #knust
In this video we are going to learn how to solve circuit problems using Thevenin's theorem.
Thevenin's theorem states that any linear circuit connected between two terminals can be replaced by a Thevenin's voltage Vth in series with a Thevenin's resistance Rth.
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 Vth using KVL
3. Deactivate all independent sources, open circuit current sources and short circuit voltage sources and find the Rth
4. Produce the Thevenin's equivalent circuit and reconnect the resistor you removed.
5. Find the current through the resistor using the formula I = Vth/(Rth + Rl)
