AI Thread Summary
In the circuit analysis, components A and B are identified as power sources, while components C, D, and E are absorbing power. Using Kirchhoff's Voltage Law (KVL), the voltages across the components were calculated, resulting in VA being 12V and VD being 10V. The power calculations yielded PA at 60W, PB at 15W, PC at 25W, PD at 30W, and PE at 20W. The total power delivered by the sources equals the total power absorbed, confirming that conservation of power is satisfied. The analysis demonstrates a clear understanding of power distribution in the circuit.

Homework Statement



For the figure:
https://sphotos-b.xx.fbcdn.net/hphotos-ash3/60194_493555593997294_154034279_n.jpg

a.Determine which components are absorbing power
and which are delivering power.

b. Is conservation of power satisfied? Explain your
answer.

Homework Equations



P = IV

KVL

The Attempt at a Solution


First I go through the smaller right loop with D and E
use KVL I have VD = 10V

Use the bigger loop ABEC
-10V - 5V + VA + 3V = 0--->VA = 12V

Based on the current flow A and B are the source and the rest are absorbing power.
simultaneously solve for all the power:
PA = 60w
PB = 15w
PC = 25w
PD = 30w
PE = 20w

PA + PB = PC + PD + PE
=> so the conservation of power is satisfied.
