Calculate the work done by a Generator

AI Thread Summary
The discussion revolves around calculating the work done by a generator in moving one mole of electrons from a potential of 9.00 V to -5.00 V. The initial confusion stems from the participant's lack of understanding of electromagnetism concepts, particularly the relationship between charge and voltage. It is clarified that one mole of electrons corresponds to a Faraday, which is a specific amount of charge. The formula for work is provided as the product of charge and the change in voltage. The participant is encouraged to apply this formula to solve the problem.

Homework Statement



How much work is done by a generator or some other source of potential difference in moving 1 mole of electrons from an initial point of electric potential 9.00 V to where the potential is -5.00 V


Homework Equations



Im sure what to do



The Attempt at a Solution



I calculated the molecular weight of 1 mole of electrons, 5.49 x 10^-21 kg. Then I got extremely stumped. I'm a beginner at electromagnetism so I am not sure what to do at this point.

A mole of electrons is a Faraday. You might want to look up how many coulombs a Faraday is. This is a measure of charge.

As to Work that is generally just charge * change in voltage. (Vf - Vi) * coulombs
 
thanks i really appreciate your help
 

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...
