## Homework Statement

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 :(
