How Do You Calculate Charge on Capacitors in a Circuit?

AI Thread Summary
The discussion focuses on calculating the charge on capacitors in a circuit with four capacitors connected between points a and b. The equivalent capacitance was calculated to be 6.54μF, and the charges on the 24.0 μF and 7.00 μF capacitors were found to be 108 μF and 84.0 μF, respectively. However, the charge calculated for the 2.00 μF capacitor was incorrect at 24.0 μF, and assistance is requested for this and another capacitor with a capacitance of 14.0 μF. Participants suggest verifying calculations, particularly for the equivalent capacitance, to identify errors. Accurate calculations are crucial for determining the correct charge on each capacitor in the circuit.

Homework Statement



Four capacitors are connected as shown in the figure below:

The Attempt at a Solution



(a) Find the equivalent capacitance between points a and b.
I found it to be 6.54μF.

(b) If ΔVab = 16.5 V calculate the charge on the the 24.0 μF capacitor.
108 μF (correct)

(c) If ΔVab = 16.5 V calculate the charge on the the 7.00 μF capacitor.
84.0 μF (correct)

(d) If ΔVab = 16.5 V calculate the charge on the the 2.00 μF capacitor.
I got 24.0 but its not correct.

(e) If ΔVab = 16.5 V calculate the charge on the the capacitor C, which equals 14.0 μF.
Likewise here.

Any help on parts d and e is appreciated.

You should start by checking your calculations for part(a); I get a slightly different answer than you. If you show me your work, I can show you where you went wrong.
 

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'

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...
