AI Thread Summary

To prove the equation I=(V(sub b))/R*e^-t/RC experimentally, one should use a function generator to charge a capacitor and collect relevant data. Plotting the voltage (V) against time (t) and voltage against e^-t/RC is essential for visualizing the relationship. Analyzing these graphs will help demonstrate the exponential decay behavior of the current as the capacitor charges. The provided HyperPhysics link offers a useful reference for understanding the theoretical background of capacitor charging. Properly interpreting the plotted data will validate the equation experimentally.

1. I've been tasked with proving I=(V(sub b))/R*e^-t/RC on charging capacitor experimentally, with a function generator.
2. Can you explain the graph here http://hyperphysics.phy-astr.gsu.edu/hbase/electric/capchg.html

Well, I have a dataset, and now, uh, what? How do I prove this monster with data

Plot your data, both V vs t and V vs e^-t/RC.

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 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'

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...
