Homework Statement
Graph of current vs voltage. What is happening to the resistance after the linear portion of the graph and why.
Homework Equations
none
The Attempt at a Solution
the line is the resistance and it follows ohms law for a while (it is constant and independent of V and I), but then suddenly jumps up exponentially at a high value of I... I can't figure out what could cause this. it doesn't say whether this resistor is ohmic or not, but graphs of nonohmic resistors I've seen are exponential all the time not just at high current
