P.2.11 The potentiometer R 5 of the circuit diagram of Figure 2.110 varies over the range
0 ≤ R 5 ≤ 100 Ω in linear increments of 5 Ω. Write a MATLAB program that returns
the following plots:
a. R 5 versus I 1
b. R 5 versus I 2
c. R 5 versus I 3
d. R 5 versus I 4
e. R 5 versus I 5
P.2.12 Repeat P.2.11 for the following cases:
a. R 5 versus V R1
b. R 5 versus V R3
c. V R1 versus V R5
d. V R3 versus I 5
P.2.13 For the circuit diagram shown in Figure 2.110, write a program that returns the following plots:
a. R 5 versus power of R 3
b. R 5 versus power of (R 1 ||R 2 )
c. R 5 versus power of (R 4 ||R 5 )
d. R 5 versus power of (V)
P.2.14 For the circuit shown in Figure 2.110, write and run a program that returns the following
plots as R 5 varies over the range 0 ≤ R 5 ≤ 100 Ω in linear increments of 5 Ω:
a. V R3 versus V R1
