(1) Ohmic resistor obeys ohm's law i.e., V/I is constant for all values of V or I; whereas Non-ohmic resistor does not obey ohm's law i.e., V/I is not same for all values of V or I. (2) In Ohmic …

Let resultant resistance of this parallel combination is R. By applying the Ohm's law to the whole circuit, we get that. I=V/R. Since the potential difference across all the resistances is same, so …
