- Finding currents through resistors
- Relevant Equations
- R(eq. parallel) = (1/R1 + 1/R2 + …)^-1 and R(eq. series) = (R1 + R2 + …) and E=IR
I'm taking a break from music for a few days because I do that sometimes, and it's like a rule for me, and I usually listen to music when doing my physics homework. I'm realizing I have a little more trouble without that boost I get. But it could also be that what I'm trying to do is hard. I think I really need to work on circuit solving if I want to get a B in this class.
The specific circuit I was having trouble with is:
I don't think I need to include the specific values, but the battery voltage and the resistance values for each resistor are given.
I tried breaking the circuit up into loops, but that doesn't seem to work very well. The problem asks what the currents going through each resistor are. I don't know how to find those values or the voltage drops.
I guess I can find the voltage drops if I can find the currents - because they would just be the currents times the given resistances, right? R34 is in parallel with R2 and R234 is in parallel with R1. So V34 = V2 and V234 = V1? Is V134 = V2?
Is I3 = I4 = I(eq.) for the entire circuit?
If somebody could help me understand how to apply E = IR along with the rules for parallel and series circuits that would help immensely.
