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 V

_{D}= 10V

Use the bigger loop ABEC

-10V - 5V + V

_{A}+ 3V = 0--->V

_{A}= 12V

Based on the current flow A and B are the source and the rest are absorbing power.

simultaneously solve for all the power:

P

_{A}= 60w

P

_{B}= 15w

P

_{C}= 25w

P

_{D}= 30w

P

_{E}= 20w

P

_{A}+ P

_{B}= P

_{C}+ P

_{D}+ P

_{E}

=> so the conservation of power is satisfied.
