DC Circuits Question (internal resistance)

AI Thread Summary
The discussion revolves around calculating the currents through resistors R1 and R2 in a circuit with given voltages and resistances. The correct current through R1 is calculated as approximately 0.162 A, while the current through R2 is initially calculated as 0.375 A, which is later questioned as potentially incorrect. Participants suggest that there may have been a mix-up with the resistor values, indicating the need for careful application of Kirchhoff's Voltage Law (KVL) to verify the results. The importance of correctly identifying resistor values and applying fundamental circuit laws is emphasized for accurate calculations. The conversation highlights the common challenges faced in circuit analysis.

Homework Statement



Determine the magnitudes and directions of the currents through R1 and R2 in Fig. 19-47, where R1 = 37 and R2 = 16 .

Figure 19-47
(image attached)

V1 = 9.0 V
V3 = 6.0 V
R1 = 37 \Omega
R2 = 16 \Omega

Homework Equations



V = IR

The Attempt at a Solution



V = IR
6.0 V = (37\Omega) I
.16216 A = I _{}1(correct)

V = IR
6.0 = (16\Omega) I
.375 A = I_{}2 (incorrect)

That's weird, I would say I1 is incorrect and I2 is correct. Did you get the 16Ω and 37Ω values reversed perhaps?

Kirchof's Voltage Law (KVL) would be useful here.
 
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'
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...
