For the circuit shown in Figure P2.22: a. Determine whether each component is absorbing or delivering power. b. Is conservation of power satisfied? Explain your answer.
What will be an ideal response?
Known quantities:
Circuit shown in Figure P2.22.
Find:
a) Determine power absorbed or power delivered
b) Testify power conservation
Analysis:
By KCL, the current through element B is 5A, to the right.
By KVL on the outer loop, .
Therefore, the voltage across element A is
(positive at the top).
A supplies
B supplies
C absorbs
D absorbs
E absorbs
Total power supplied =
Total power absorbed =
Tot. power supplied = Tot. power absorbed
?conservation of power is satisfied.
