Thevenin Equivalent: Solving Circuit Problems

AI Thread Summary
To find the Thevenin equivalent of the circuit, the open-circuit voltage must be determined. It is confirmed that no current flows through resistor R3 when the circuit is open, as it leads to a dead end. Consequently, the potential difference across R3 is zero. This simplifies the calculation of the open-circuit voltage, making it easier to derive the Thevenin equivalent. Understanding these principles is crucial for solving circuit problems effectively.

I'm trying to find the Thevenin equivalent of the circuit on the left side and but having trouble in getting the open circuit voltage.

Does no current flow through R3 since that way leads to a dead end?

How could any current flow through R3?
There is no way to go for any current.
Therefore the open-circuit voltage is easy to calculate.

Yes, no current flows through R3 when the circuit is "open". If no current flows, what is the potential difference between the terminals of that resistor?

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...
