Question

sketch the I-V graph of a subtance that obeys ohm's law.

Answer 1

It's a linear graph. :)

Answer 2

its a straight line in cartesian co-ordinates

Answer 3

but how do i graph it? haha

Answer 4

can anyone show me the graph ?

Answer 6

In the graph I linked, the red line has lowest resistance R, because it has larger current for the same voltage than the other two curves.

Answer 7

how about the two line?
