Lab 9 (3/24): Maximum Power Transfer

Maximum Power Transfer

Per-Lab: we do a pre-lab finding the power of a source when it is ideal and not ideal.


We  measured  the resistor for R1 and R2, and the voltage, then got the Rs for both.

The circuit set up for the experiment.

To find the R when Pmax,  it is differetial dP/DR, so we got Rth=RL.

So when we used R1=RL=2.2K Pmax=2.8mW


We measured the voltage which across the R.

Wo got the % different for the power.
