Write the anme of the cell which is generally used in transistors. Write the reactions taking place at the anode and the cathode of this cell.

Text Solution

Verified by Experts

Dry cell is generaly used in transistors.
Reaction of cell taking place at anode and cathode are:
At anode: `Zn(S)toZn^(2+)+2e^(-)`
At cathode: `2MnO_(2)(S)+2NH_(4)^(+)+2e^(-)toMn_(2)O_(3)(S)+2NH_(3)(g)+H_(2)O`
