SUMMARY
The maximum power transfer theorem states that maximum power is delivered to an external resistance when it equals the internal resistance of the source. In this discussion, the relationship is derived using the formula P = I^2 * R, where I is the current calculated as I = E/(R + r). By differentiating the power equation with respect to external resistance R and setting the derivative dP/dR to zero, the condition for maximum power delivery is established. This principle is crucial for optimizing circuit performance in electrical engineering.
