AI Thread Summary
To calculate the current flowing through resistor R1 in the circuit with a 12-volt battery and resistors R1 (9 ohms), R2 (6 ohms), and R3 (5 ohms), first determine the equivalent resistance. The equivalent resistance can be found by combining the resistances in series and parallel as appropriate. Once the total resistance is calculated, Ohm's Law (V = IR) can be applied to find the current. The user expresses confusion about the process and seeks guidance on finding the equivalent resistance. Understanding these concepts is crucial for solving the problem effectively.

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...
