Hello there, first post here. I am a Mechanical Engineering student and am taking a mandatory circuits class. This is a homework problem, but I not not fishing for the answer, I just need some help to get to the answer.
I have a series circuit with voltage source and 2 resistors. very simple circuit.
Given:
Vsource=24V
Power=48mW
Found:
Itot=P/V=2mA
Req=V/I=R1+R2=12Kohms
Still need to find individual values for R1, R2, V1, and V2.
Relevant equations:
P=IV=I^2R=V^2/R
V1=I*R1
V2=I*R2
Vs=V1+V2
V=IR
I=V/R
R=V/I
R1=V1/I
R2=V2/I
Voltage Divides.
Current is constant.
The problem before this one was a parallel circuit the same way. I found all those values after an hour of crunching. I'm trying to apply the same thinking to this one, but I feel I may be overthinking it.
I have been on this for hours, running in circles.
I have tried to manipulate the Power and Ohms Law equations every way possible to solve a system. But, it seems what I am trying to solve for always cancels out, or I end with up 1. But, I believe this would be a system with 4 unknowns, 4 equations?
Does that seem correct? Any help would be absolutely appreciated. I do not like circuits, but am trying to understand and apply the concepts.
Thanks!
