If the charge on a capacitor doubles how does its capacitance change?

AI Thread Summary
Doubling the charge on a capacitor does not change its capacitance, which is determined solely by the geometric configuration of the conductors. The relationship between charge (Q), capacitance (C), and voltage (V) is expressed by the equation Q=CV. While increasing the charge affects the potential difference across the capacitor plates, it does not alter the capacitance itself. Capacitance remains constant regardless of the amount of charge applied. Understanding this principle is crucial for accurate analysis in electrical engineering.

Does it double or stay the same?

The capacitance depends only on the geometrical configuration of your conductors (capacitors). It doesn't matter HOW much charge you put there, the capacitance remains the same.
 
Q=CV

Capacitance depends on 'area and length' of the capacitor , the charge on it won't change the capacitance but would change the potential difference on the plate.
 
I can't believe i could have written such crap. :I must be having a miserable day.

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...
