Choose which of the following would a typical Ohmic conductor look like.

According to Ohm's rule, if all other physical parameters and temperatures remain constant, the voltage across a conductor is precisely proportional to the current flowing through it.

Because they follow Ohm's law, the bulk of metals is ohmic conductors. However, semiconductors are not ohmic. A straight line running through the origin can be seen in the V-I characteristic of the ohmic conductor nichrome metal.
