  Experiment Name: Verification of Maximum Power Transfer Theorem 1. OBJECTIVE To verify the Maximum Power Transfer Theorem in a DC network and to prove that maximum power is delivered to the load (R_L) when it is equal to the internal resistance (R_i) of the source.   2. APPARATUS REQUIRED DC Power Supply: 0–30V Fixed Resistor (R i ): 100 Ω Decade Resistance Box (R L ): 0–500 Ω Digital Multimeter: 2 units (to measure current and voltage) Breadboard & Wires   3. CIRCUIT DIAGRAM 4. THEORY The Maximum Power Transfer Theorem states that for a network to deliver maximum power to a load, the load resistance (R_L) must be equal to the internal resistance (R_i) of the source as seen from the load terminals. Power delivered to the load: P = I² × R L Where I = V / (R i + R L ) Maximum power occurs when dP/dR L = 0, leading to R i = R L . 5. OBSERVATION TABLE Constants: Source Voltage (V) = 10V, Internal Resistance (R_i) = 100 Ω ...
