    Resistance Resistor
AI Thread Summary
The discussion centers on determining the resistance of a resistor using a variable voltage source. The relationship between voltage (V) and current (I) is established through the equation R=V/I. Participants confirm that since the graph is linear, the slope of the line represents the resistance. Therefore, the slope of the line can be used to calculate the resistance in the specified current range of 1-4 Amps. This confirms that the slope indeed corresponds to the resistance value.

Homework Statement


q6.jpg

Basically, this "battery" is actually a variable voltage source. The current is raised and the voltmeter measures the voltage in the resistor. What is the resistance in the region that the current goes from 1-4 Amps? (BTW, the red line is a best fit line.)


Homework Equations


R=V/I


The Attempt at a Solution


Ok, well since this is linear, the slope of this line is actually V/I, so would the slope of the line be the resistance?

Yes it would be the slope of the line.
 

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...
