P.2.33 The switch shown in Figure 2.126 has been at (position) a for a very long time. At
t = 0, the switch is moved from position a to position b, where it remains indefi -
nitely. Write a program that returns the following plots:
a. i 1 (t) versus t, i 2 (t) versus t, and i 3 (t) versus t
b. v L (t) versus t and v C (t) versus t over the range 0 < t < 6 s
P.2.34 For the two circuits shown in Figure 2.127, determine the Thevenin’s and Norton’s
equivalent circuits as seen from terminals A and B.
P.2.35 Calculate, for each of the circuits shown in Figure 2.127, the value of the resistor that
connects across terminals AB, will dissipate maximum power.
P.2.36 For the circuit shown in Figure 2.128, calculate I by using
a. Node equations
b. Loop equations
c. Source transformations
d. Superposition principle
e. Thevenin’s theorem
f. Norton’s theorem
