Current Resistor

AI Thread Summary

To calculate the current through a resistor using the number of electrons passing over time, the formula I = Q/t is used, where Q is the total charge in coulombs. Since each electron has a charge of approximately 1.602 x 10^(-19) coulombs, the total charge can be found by multiplying the number of electrons by this value. The current can then be determined by dividing the total charge by the time in seconds. Brad's initial calculation of current was incorrect due to misunderstanding the relationship between charge and current. Understanding these principles is essential for accurate electrical calculations.

Hi all,
I need to find the current through a resistor knowing the # of electrons passing through it over a given time, t. Can someone help me out with this?
I thought it was just I = #elec/time, but this cannot be right (i'm getting values along the lines of 1.5E19 Amps)

Thanks,
Brad

1 Amp = 1 Coulomb/Sec
{Electron Charge} = 1.602x10^(-19) Coulombs

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
