AI Thread Summary
The discussion focuses on calculating current and potential difference in a circuit with given resistances and an ideal battery. The user references a previous problem for guidance but encounters difficulties applying the same method. Key points include determining the current through the resistor and ammeter (I1) and the relationship between total current (I) and the readings on the ammeter and voltmeter. The calculations involve understanding how current divides in the circuit and the inverse relationship between current and resistance. The thread emphasizes the importance of correctly identifying the connections and applying the principles of circuit analysis.

Hello everyone, I'm suppose to find the current and potential difference, I did a smilar problem to this that Chi helped me on, and it worked out, i applied the same method but didn't work out right. Here is the question and under it is my work:

Question:
the ammeter and voltmeter resistances are 2.00 and 268 , respectively. Take E= 12.0 V for the ideal battery and R0 = 119 .

Picutre of Figure b: http://www.webassign.net/hrw/28-40b.gif

(a) If R = 93.0 what will the meters read for the two different connections (Figs. 28-40b)?
Figure B:

I = ?A
Potential Difference = ? V

Thanks!

I only see one connection which is the one in our drawing. anyway, it looks like you pretty much solved it! You know the total I so you just have to find how much of it goes through the R and A (call that I1), and how much goes through V (I2, I1+I2 = I, remember that the I and resistance are inversly related). I1 would be the reading for the ammeter, and I1 times the total resistance of A and R is the reading for the voltmeter.
 
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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
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...
