SUMMARY

The discussion focuses on calculating the power absorbed by each element in a given electrical circuit. The user correctly identifies the current through the resistor R(L) as -3A, leading to a voltage of 66V across it, resulting in a power absorption of 198W. The user also calculates the power absorbed by the source V(S) as 8/11W and attempts to verify the power balance in the circuit. However, confusion arises regarding the conservation of power, as the total power generated does not equal the total power absorbed.

Homework Statement


For the following circuit, determine the power absorbed by each element

2. The attempt at a solution

This sign convention stuff is realllly confusing me.
Can someone give me some direction here?

The current through I(s) is -3A, this implies that there is 3A flowing in the opposite direction yeah? Hence there is 3A flowing into R(L).

The voltage across R(L) must then be: V[R(L)]= IR = 3 x 22 = 66V
Hence the power absorbed by R(L) is: P[R(L)]= VI = 66 x 3 = 198W


Here is where I start to get confused.
The total resistance around the circuit must be 22 ohms right?

The current through V(S) must then be I = V/R = 4/22 A
P(S) = VI = 4 x (4/22) = 8/11 W

The voltage through I(S) => V = IR = -3 x 22 = -66V
Hence the power absorbed by I(S) is: P[I(S)] = VI = -66 x -3 = 198W

Now I was under the impression that the Power generated must = Power abosrbed.
That doesn't work here ...

I'm not sure how much of this is right, but any help would be greatly appreciated.
Cheers
