Thevenin’s Theorem
Thevenin’s Theorem states that any linear two–terminal circuit consisting of several voltages and resistances can be replaced by a single voltage (Vt) in series with a resistance connected across the load (Thevenin Resistance).
Here Vt is open – circuit voltage at the terminals.
Steps for using Thevenin’s Theorem
Step 1: First, we will remove the Load Resistor from the circuit.
Step 2: Then we will Calculate the Thevenin Voltage.
Step 3: Replace the power sources with short circuit wires.
Step 4: Calculate the Thevenin Resistance.
Step 5: Draw the Thevenin Equivalent Circuit.
Solved Example
Q. Find the Current I Through R=2Ω for The Circuit given below using Thevenin’s Theorem
After Removing R=2Ω Circuit will be
-50+25I=0
I=2A
Hence,[Tex]V_{ab} [/Tex]=20xI=40V
To find [Tex]R_{th} [/Tex] we deactivate Voltage Source
[Tex]R_{th} [/Tex]=(5Ω||20Ω)+4Ω
[Tex]R_{th} [/Tex]=8Ω
So the Thevenin’s Circuit will be
[Tex]I=\frac{40}{10}=4V [/Tex]
