Resistor Network Circuit Analysis

AI Thread Summary
The discussion revolves around a request for assistance with resistor network circuit analysis, specifically regarding the calculation of equivalent resistance, current through the battery, current through each resistor, voltage on each resistor, and power used by each resistor. The user has provided a diagram with labeled resistors and is uncertain about the values, particularly R3, which is listed as both 5 ohms and 6 ohms. There is also confusion about the battery voltage, questioning whether it is 12V or 8V. The user suspects errors in their calculations and seeks clarification on these points to resolve their issues. Accurate identification of resistor values and voltage is crucial for correct circuit analysis.

Could someone help me with number 1. I think I did it wrong. I attached the diagram with the labels. On the original one the resistors aren't labeled, but I separately labeled them on my diagram.

1. R1=1.0 ohms
R2=3.0 ohms
R3=5.0 ohms
R4=12 ohms
R5=2.0ohms
R6=4.0 ohms
R=0.2 ohms
Vbatt=12.0 V

1. Homework Statement . I need to do determine the following:
a. Equivalent reistance
b current through the battery
c. The current through each resistor
d. the voltage on each resistor
e.the power used by each resistor

I really suspect I did something wrong.

Scan 11 is with the resistors labeled and breaking them down.
Scan 14 and 15 is of my work. If you can figure out what I did wrong that would be great!

Image 1 is of the initial problem.

Homework Equations

My equations are on the scans.

The Attempt at a Solution



I definitely attempted the solution on the scans attached.

I need help ASAP. Thanks!
 
Is R3 5 Ohms as you've listed in the problem statement or 6 Ohms as shown on the diagram?
 
Assuming R3 = 6Ohms..

Sheet 11 looks ok Req = 7.2R

Is Vbat 12V or 8V ?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
