Transformers

AI Thread Summary

When an alternating voltage is applied across the primary coil of a transformer, an electromotive force (emf) is indeed induced in the secondary coil, making the first statement true. This induced emf leads to an alternating current in the secondary coil, confirming that the second statement is also true. The operation of transformers is based on Faraday's law of electromagnetic induction, which explains how changing magnetic fields generate voltage. Key equations include the transformer equation, which relates primary and secondary voltages and turns ratios. Understanding these concepts is essential for grasping transformer functionality.

1. when an alternating voltage is applied across the primary coil, an emf is induced in the secondary coil
2. when an alternating voltage is applied across the primary coil, an alternating current is induced in the secondary coilcan anyone tell me which one is true and why?

Thanks a lot.

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:
