Which of the following is NOT a characteristic of primary cell?

  • A.Cheaper than secondary cell
  • B.Light in weight
  • C.Rechargeable
  • D.Can not supply large voltage

Answer: C

'Rechargeable' is not a characteristic of a primary cell. A primary cell is used once and then thrown away, because its chemical reaction cannot be reversed by passing a current back. Rechargeable cells are secondary cells.

A primary cell is cheaper than a secondary cell, light in weight, and gives a small voltage and current, as the other options say. So the third option is the one that is not a characteristic.
