The discussion revolves around circuit analysis involving series and parallel circuits, specifically focusing on calculating equivalent resistance and current values in a given circuit diagram with a 10V supply.
Some participants have provided guidance on calculating potential drops and currents based on the known values, while others are exploring different interpretations of the circuit parameters. There is an ongoing exchange of detailed calculations and checks on the values obtained.
Participants mention the importance of significant figures in calculations and the need for detailed work to verify results. There is a focus on understanding the relationships between currents and potential drops in the circuit.
For I1 can I use 10V or do I need to find V1 by using the current I found? Also, to find Req for the other resistors do I need to add the 10 ohm and 5 ohm resistors and then solve the Req using the two parallel?berkeman said:Your Req is correct (well, I would keep more significant figures for more calculations). So now you know the current drawn from the 10V supply. That current flows through R1, so that gives you all you need to know about R1. Now calculate the Req for the resistors past R1 so you can see how the current divides between the two branches, and keep on going with the calculation. Please show your detailed work so we can keep checking it. Good so far!
We've learned Kirchhoff's laws.gneill said:
The potential drop off across R1 is 3.7 V. The current through R2 is 0.185. The current through R3+4 is 0.25gneill said:
Your potential drop across R1` is okay, but the other current values do not look good. What are you taking as the potential at node Va? It's certainly not the potential drop across R1!joshqg said:
