$A$ moving coil galvanometer has $150$ equal divisions. Its current sensitivity is $10 \text{ divisions per milliampere}$ and voltage sensitivity is $2 \text{ divisions per millivolt}$. In order that each division reads $1 \text{ V}$,the resistance in ohms needed to be connected in series with the coil will be

At the anode,the process of $......$ occurs,and at the cathode,the process of $......$ occurs.

Write a note on the $Ni-Cd$ cell.
