AI Thread Summary
When touching the terminal of an 18V truck battery with a body resistance of 100,000Ω, the current (I) can be calculated using Ohm's Law. The initial calculation yields I = 18/100,000, resulting in 0.00018 A or 180 µA. However, there is a suggestion to double-check the math and clarify the units for the result. The discussion emphasizes the importance of correctly applying Ohm's Law and ensuring accurate unit specification. Overall, the calculation process and the need for precision in electrical measurements are highlighted.

The result of the math seems to be a bit off given the values, although the equation is of the correct form :smile: (you should specify the units for the result, too).

Look up Ohm's Law and then take another look at the problem.
 
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...
