A Voltage Divider Calculator is the latest addition to the CAFViewer. Pat uses the calculator to illustrate the “Maximum Power Transfer Theorem” which states that an impedance-matched interface transfers the most power from a source to
Amplifier power ratings are good for window shopping and water cooler chats. If you need to drive a real-world 4 ohm Load, you need the matrix.
Long ago, 8 ohms was established as a practical impedance for
