What do we mean by "Ohmic"?

a. "Ohmic" is when the plot of V [Volt] versus I [Amp] yields a linear relationship through the origin, or function.
b. For each current there is one voltage value associated with it. "Ohmic" is when the plot of V [Volt] versus I [Amp] has a slope equal to 1/R.
c. "Ohmic" is when the plot of I [Amp] versus V [Volt] has a slope equal to R.
d. "Ohmic" is when a device does not allow current flow; it is an insulator not a conductor.

Answer:

c. "Ohmic" is when the plot of I [Amp] versus V [Volt] has a slope equal to R.

Explanation:

A resistor is said to be Ohmic if it obeys ohms law. In am Ohmic resistor, the resistance is constant regardless of the current passing through it. Graphically, an ohmic resistor as a linear relationship when its current and voltage relationship is presented graphically.
