Question B-006-006-004

When will a power source deliver maximum output to the load?

Correct Answer

When the impedance of the load is equal to the impedance of the source

Explanation

The Maximum Power Transfer Theorem states that maximum power is transferred from a source to a load when the load impedance is the complex conjugate of the source impedance (or purely resistive and equal if source is purely resistive).
