Refer to Figure P2.68 and assume vS = 15 V, R1 = 12 ? , R2 = 5 ? , R3 = 8 ? , R4 = 2 ? , R5 = 4 ? , R6 = 2 ? , R7 = 1 ? , and R8 = R9 = 10 ? . Find:

a. The number of nodes in the circuit.

b. The power delivered by the source vS .

c. The equivalent resistance seen by the source vS .




Known quantities:

Circuit of Figure P2.68.

R1=12?, R2=5 ?, R3=8 ?,

R4=2 ?, R5=4 ?, R6=2 ?,

R7=1 ?, R8=R9=10 ?, vs=15V



Find:

The number of nodes in the circuit.

The power delivered by the voltage source.

The equivalent resistance seen by the voltage source.



Analysis:

Count the nodes:

Nodes=6

See nodes A, B, C, D, E, & F above



R9 is eliminated due to the short.

Start at the right and work left:
