AI Thread Summary
To find the potential difference Vab in parallel circuits, it's essential to remember that the voltage across all parallel elements is the same. The current in each branch must be calculated, which will then allow for determining the potential difference. Once the voltages Va and Vb are established, Vab can be calculated. Additionally, it's noted that the original post was made in the wrong forum, as there are dedicated homework forums for such queries. Properly identifying the right platform for questions can enhance the likelihood of receiving accurate assistance.

I hope that this one will be ok.
 


You've posted this in the wrong forum. There are homework forums for that. You only need to work out the current in each parallel branch, bearing in mind that the voltage across parallel elements are the same. Then with the current, you can find the potential difference and hence Va and Vb. Then with both Va and Vb you can find Vab.
 


thanks mate!
 

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...
