What does “Types of cells” actually mean in Electrochemistry, and why does it matter for JEE?
a galvanic cell turns a spontaneous reaction into electricity; an electrolytic cell uses electricity to drive a non-spontaneous reaction.
In simple words: a galvanic cell turns a spontaneous reaction into electricity; an electrolytic cell uses electricity to drive a non-spontaneous reaction. Getting Types of cells clear matters because JEE questions on Electrochemistry usually test this idea directly, not just a formula you memorised.
Key point
Types of cells
Common mistake
swapping which cell is spontaneous.
Memory tip
galvanic = battery (gives energy); electrolytic = needs a power source.
