Maximum Power Transfer Lab

Source Voltage \(V_{th}\) 12

Internal Resistance \(R_{th}\) 10

Load Resistance \(R_{L}\) 5

Total Resistance \( R_T = R_{th} + R_L \)	-- Ω
Line Current \( I = \frac{V_{th}}{R_T} \)	-- A
Power to Load \( P_L = I^2 \times R_L \)	-- W
Efficiency \( \eta = \frac{R_L}{R_T} \times 100 \)	-- %
Theoretical Max \( P_{max} \)	-- W

Note: Power delivered is maximum when internal resistance matches load resistance: \( R_L = R_{th} \).
