Question
Write the name of the cell which is generally used in transistors. Write the reactions taking place at the anode and the cathode of this cell.
Solution
The dry cell (also known as Leclanche cell) is used in transistors.
The reactions taking place at the anode and cathode are given below.
At anode: Zn(s) → Zn2+ + 2e−
At cathode : `MnO_2 + NH_4^+ + e^(-) -> MnO(OH) + NH_3`
