Circuit interconnection: power delivered

Click For Summary
SUMMARY

The discussion centers on the interpretation of power delivered in circuit interconnections, specifically regarding independent voltage and current sources. Participants clarify that power delivered refers to the sum of powers produced by sourcing components rather than sinking ones. The ambiguity in defining "the circuit" complicates the analysis, as it can involve one to four components, affecting the calculation of power delivered. The conversation emphasizes the importance of clear definitions and complete information in circuit analysis.

PREREQUISITES
  • Understanding of independent voltage and current sources
  • Basic knowledge of circuit analysis techniques
  • Familiarity with power calculations in electrical circuits
  • Ability to interpret circuit diagrams
NEXT STEPS
  • Research the concept of power in electrical circuits, focusing on sourcing vs. sinking components
  • Study the principles of circuit analysis, including Kirchhoff's laws
  • Learn about the role of voltage and current sources in circuit design
  • Explore different interpretations of circuit configurations and their implications on power calculations
USEFUL FOR

Electrical engineering students, circuit designers, and anyone involved in analyzing power delivery in electrical circuits will benefit from this discussion.

The circles are referring to independent voltage or current sources, which maintain the same current/voltage regardless of the rest of the circuit.

I'm confused because power delivered means they want the value of the "negative" power, which would mean only i*v1 would be the only power delivered, however this answer is wrong.

Can someone explain to me if I'm missing something here? Thank you

Hi Jenny08,

Perhaps they want the sum of the powers produced by sources that are sourcing rather than sinking it. What is the potential drop across the current source?
 
The definition of "the circuit" is very unclear. You have 4 components in the diagram, different interpretations of "the circuit" could mean 1, 2, 3, or 4 of them. Are you sure that is all the information you are given?
