{40LA O 7.5A
a. Label and show the essential nodes in the circuit. How many essential nodes
are there & how many simultaneous equations can be obtained?
b. Use node voltage method and solve for all node voltages.
c. Calculate the power associated with all the sources in the circuit (50V, 2A,
10A sources).
d. From part-c calculation, mention if each of the sources are delivering or
absorbing power in the circuit.
e. Calculate the currents flowing through each of the resistor (15 Q, 10 Q,
30 Ω, 25 Ω, 60 Ω resistors ).
f. Calculate the powers associated with each of the resistor.
From part-f calculation, please state if the powers associated with the
g.
resistors are being absorbed or delivered.
h. From part-c and f calculations, what is total power absorbed and total
power delivered/generated in the circuit? Are they equal to one another (Check
if total power generated = total power absorbed).
