What is the difference between ohmic conductor and non-ohmic conductor? Give
one example each and draw their IV characteristic curves.
Ohmic vs Non-Ohmic Conductors
Ohm’s law, discovered and named after Georg Ohm, states the relationship between voltage, current and resistance of a conductor. This is important in designing electrical and electronic circuits in order ensure that the voltages and currents in the components stay within specs. Just about any component that is capable of carrying a current is considered to be a conductor, it’s just a matter of whether the conductor is Ohmic or not. The main difference between an Ohmic and a non-Ohmic conductor

A parallel plate capacitor is made of two rectangular aluminium sheets of lateral dimensions 500 mm and 20 mm. The space between the plates is filled with
polystyrene and the separation between plates is 0.15 mm. Calculate the capacitance of the capacitor and the value of the maximum potential difference that can be applied across the capacitor without dielectric breakdown. Take the dielectric constant of polystyrene as 2.6 and the value of the maximum electric field that
polystyrene can withstand as 25×106 Vm−1.
