3. Solve the maximum power transfer problem for a dc circuit which consists of a power supply V_dc = 10 volts with an internal resistance R_s = 200 ohms (measured at the room temperature 20 degree C).

Write MATLAB programs to solve the following problems:

1. Find the value of the internal resistance of this circuit at 60⁰C. Use disp() or fprintf() to display the value.

R_T1, the resistance at a temperature T₁, is determined by formula

R_T1 = R₂₀ [1+0.00393 x (T₁-20)], where R₂₀ is the resistance at 20⁰C

2. The internal resistance Rs is 200 ohms. Find the value of load resistance RL that will result in the maximum possible power being supplied by the source to the load.
3. Power-vs-RL with title, grid, x-axis, and y-axis info. X axis for RL, Y axis for Power.
