Expert Answer:

 
Active electrodes are electrodes which take part in a chemical reaction. They can either be oxidised or reduced in the half cell reaction.
 
Example: Zinc electrode, copper electrode
 
Inactive/ Inert electrodes are electrodes which transfer electrons rather than exchanging ions with the aqueous solution in which they are immersed.
They does not take part in any chemical reaction.
 
Example: Platinum electrode, Graphite electrode.
