AI Thread Summary
The discussion revolves around calculating the percentage of charge transferred from capacitor C1 to capacitor C2 in a parallel circuit. C1, with a capacitance of 0.05 µF, is fully charged to 2 x 10^-8 C at 0.4V, while C2, with a capacitance of 0.1 µF, starts uncharged. The original poster initially believes the transfer is 100% but later realizes it is actually 70%. Participants emphasize the importance of showing calculations and thought processes to clarify misunderstandings. The conversation highlights the need for a deeper understanding of charge distribution in capacitors connected in parallel.

Homework Statement


Hi,

I have 2 capacitors c1, c2

c1=.05 uF
c2=.1 uF

Q=CV

c1 is fully charged and connected to a .4V battery in a parallel circuit
c2 is uncharged

c2 was unconnected initially to c1 but once joined c2 can receive a charge from c1.

charge on C1=2 X 10^-8

what is the % charge transferred from c1 to c2 once joined in the circuit

Homework Equations


Q=CV

The Attempt at a Solution



I thought the answer is 100% but it is 70%.

I don't get it?

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
