How does resistance change with temperature for Ohmic conductors and filaments?

AI Thread Summary
Resistance for Ohmic conductors is directly proportional to temperature, resulting in a linear relationship that passes through the origin, indicating constant resistance. In contrast, filament materials, such as tungsten, exhibit a more complex behavior where resistance increases with temperature up to a certain point before decreasing, leading to a graph with a decreasing gradient. This behavior is due to the rising resistivity of metals at elevated temperatures. Understanding these principles is crucial for Grade 11 physics, especially in preparation for exams. The relationship between resistance and temperature is fundamental in electrical applications.

How does does resistance vary with temperature for an Ohmic conductor and filament?

Homework Equations





The Attempt at a Solution


So what I know is that resistance(Ohms) against temperature(K) for an Ohmic conductor is directly proportional with the graph passing through the Origin and being a straight line.
And for a filament, the resistance is directly proprtional for a range of temperatures and then decreases with the graph having a decreasing gradient.
Note this is Grade 11 level. I HAVE AN EXAM :(

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged 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...
