Power Transfer Superposition Principle

Maximum Power Transfer Choose an RL in order to maximize power delivered to RL.

Power Delivered to the Load

Numerical Example V TH =1 V R TH =50 Ω

Conclusion! Maximum power is delivered to the load resistor when R L is equal to R TH.

Superposition Principle Process: 1.Find VR2 due to the 12V power supply. (5V is shorted to GND) 2.Find VR2 due to the 5 V power supply. (12V is shorted to GND) 3.Add VR2 due to the 5V power supply and VR2 due to the 12 V power supply.
