When voltage ‘V’ is applied across a pair of electrode (cathode and anode), a potential gradient ‘E’ is created between the electrodes. We can calculate ‘E’ as:

Q. When voltage ‘V’ is applied across a pair of electrode (cathode and anode), a potential gradient ‘E’ is created between the electrodes. We can calculate ‘E’ as:

1. E = V/d
2. E = (1/V) x q
3. E = (Vd)/q
4. None of these

Answer: E = V/d
