what would a current vs potential difference graph look like
2007-03-15 10:08:44 · 3 answers · asked by Anonymous in Science & Mathematics ➔ Physics
V=I*R
where V =potential difference
I = current
R=resistance
The graph I vs V will depend on the property of the material. For linear material i.e. where R does not depend on current/potential difference, the graph will be a straight line going through the origin.
For semiconductor diode where R is afunction of V the graph has two parts:
on the positive part of the V axis, it will be approximately an exponentially increasing function
on the negative part of the V axis it will be an almost horizontal straight line just below the V axis.
Cheers.

Potential difference V is related to current C by the formula
V = C * R where R is the resistence
In a graph, it will be a line subtending 135 degrees to the
Y axis.

well if you have your math book it should show you an example of one......hope this helps even just a tid bit.
