This option represents the formula for power when the load resistance is equal to the internal resistance. This is the condition that maximizes power transfer according to the Maximum Power Transfer Theorem.
This option represents a condition where the load resistance is not equal to the internal resistance. It is not the maximum power transfer condition.
This option represents a condition where the load resistance is not equal to the internal resistance. It is not the maximum power transfer condition.
This option represents the formula for power when the load resistance is equal to three times the internal resistance. It is not the maximum power transfer condition.
The Maximum Power Transfer Theorem in electrical circuits states that to transfer the maximum amount of power from a source (like a battery) to a load (like a resistor), the resistance of the load should be equal to the internal resistance of the source.
Here, "E" represents the electromotive force (EMF) of the battery, and "r" represents the internal resistance of the battery.
The correct statement is B. E^2/4r. According to the Maximum Power Transfer Theorem, the maximum power is delivered to the load when the load resistance is equal to the internal resistance of the source (battery).
