Question
When potential difference is applied across an electrolyte, then Ohm's law is obeyed at:
✓
Answer
High potential.
Explanation:
When voltage is applied to an electrolyte, dissociation of ions starts.
At low voltages as the voltage increases the number of ions conducting also increases making a non linear increase of current.
After a certain voltage when the ions are dissociated and no more dissociation, the electrolyte behaves as a conductor and obeys ohm's law.
Thus at high voltages, an electrolyte obeys ohm's law.
