(a) Create the circuit shown in Figure P3-45 in Multisim. Do a parameter sweep of the load resistor \(R_{\mathrm{L}}\) (arbitrarily set to \(1 \mathrm{k} \Omega\) ) from \(1 \mathrm{k} \Omega\) to \(10 \mathrm{M} \Omega\) and plot its power \(p_{\mathrm{L}}\). Using the cursor find the value of \(R_{\mathrm{L}}\) that results in the most power delivered to it.

(b) Calculate the Thévenin resistance using the lookback method that \(R_{\mathrm{L}}\) sees. How does that value compare to the maximum power observed on the Multisim graph?
