A secondary cell is one
Options
- Acan be recharged.
- Bcan be recharged by passing current through it in the same direction.
- Ccan be recharged by passing current through it in the opposite direction.
- Dcan not recharged
Correct answer
C. can be recharged by passing current through it in the opposite direction.
Step-by-step solution
In secondary cells electrode reactions can be reversed by external electric energy source, therefore, these cells can berecharged by passing electric current and used again and again. The current is passed in the direction opposite to that of the flow of current generated by the cell.
