Use "MATLAB" to compute the following:
(1) Calculate the total resistance (RT) of the circuit
(2) Determine the total current (IT) drawn by the circuit
(3) Determine the total power (PT) supplied by the battery
(4) Create a graph showing the value of the total current (IT) as the function of R1 when R1 changes from 1 ? to 16 ? With an increment of 2 ?.
