Charging a capacitor at constant rate

AI Thread Summary
Connecting the voltmeter across the ammeter and capacitor allows for accurate measurement of voltage changes during the charging process. This setup helps in plotting a graph of charge (Q) against voltage (V) while maintaining a constant current (I). The relationship Q = It is utilized to calculate charge over time. Proper connections ensure that the readings reflect the true behavior of the circuit components. Accurate data collection is essential for analyzing the charging characteristics of the capacitor.

1. Why is the voltmeter is better to be connected across the ammeter and the capacitor.
The whole circuit contains ammeter, capacitor and a resistor connected in series while the experinement is to plot a graph of Q against V by record the constant I, then Q=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 '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...
