MAXIMUM POWER TRANSFER THEOREM - states that, a load will receive maximum power from a network when its resistance is exactly equal to the Thevenin resistance of the network applied to the load. That is, 𝑅𝐿 = 𝑅𝑇𝐻 MAXIMUM POWER TRANSFER THEOREM - states that, a load will receive maximum power from a network when its resistance is exactly equal to the Thevenin resistance of the network applied to the load. That is, 𝑅𝐿 = 𝑅𝑇𝐻 𝑷 = 𝑽𝑰 𝑷 = 𝑰𝟐 𝑹 𝑽𝟐 𝑷= 𝑹 EXAMPLE 1 In the network shown below, the source has an internal resistance of 75 ohms. Determine the load power for each of the following values of load resistance: a. 0 ohm b. 25 ohms c. 50 ohms d. 75 ohms e. 100 ohms f. 125 ohms Solution Solution EXAMPLE 2 Given the network shown below, find the value of RL for maximum power to the load, and find the maximum power to the load.
