- The internal Resistance of a Voltage Source forms a Voltage Divider with a connected load, the voltage across which is
- The Power delivered to the load is
- Maximum Power (
) is transferred when - Minimum Power (
) is transferred when = 0 or
Notes
- Known as Maximum Power Transfer Theorem
- Only 50% of a source's power can be transferred to a load
- Applies to a Current Source based on Norton's and Thevenin's Theorem
