Write a program that returns the following plots:

a. I versus VAB

b. I versus VBC

c. I versus I 1

d. I versus I 3

e. I versus power (R 1  R 2 )

P.2.16 The voltage source V 0 shown in Figure 2.112, varies from 10 to 100 V in steps (incre-
ments) of 5 V. Write a program that returns the following plots:
a. V 0 versus I 1
b. V 0 versus VR 5
c. V 0 versus I 2
d. V 0 versus I 5
e. V 0 versus power of R 2

P.2.17 The diagrams shown in Figure 2.113 represent the circuit equivalent ∆-to-Y
transformations.
