AI Thread Summary
The discussion focuses on applying Kirchhoff's rules to solve a specific electric circuit problem involving terminal voltage. The user expresses difficulty in starting the problem, despite being comfortable with similar circuits. Key advice includes summing the voltage drops across each circuit element and understanding the mathematical definition of terminal voltage, which involves the electromotive force (emf) and internal resistance. Clarification on how to approach the problem is sought, emphasizing the need for a structured application of Kirchhoff's laws. Understanding these concepts is crucial for accurately determining the terminal voltage of the batteries in the circuit.

This is a problem from my physics book. We are learning Kirchhoff's rules with electric circuits and I'm at a loss at what to do here.

I apply them just fine to a three loop circuit, using some algebra:
|-/\/\-|\//\ -|
| |
|--|\--/\/\/--|
| |
|---|\--/\/\--|

Like so..where |\ is a battery and /\/\ indicate resistors. I can find the current in a similar circuit, voltage drops, etc

But this problem:

I don't know where to begin..or how to apply the rules. Can someone help me in finding the terminal voltage of the batteries??

Thanks

You have to sum the drops across each circuit element. What is terminal voltage and how is it defined mathematically for an emf E with internal resistance r for which current i is flowing out of the positive terminal?
 

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...
