Answer: 1.5 V
A dry cell is one type of electric battery, which is generally used for the home and portable electronic devices. A battery is a device that consists of one or more electrochemical cells, which converts chemical energy into electrical energy.
Types of dry cell
- The dry cell may be categorised as a primary cell or a secondary cell depending on its nature.
- The term ‘primary cell’ refers to a cell that is neither reusable nor rechargeable. When all the chemical reagents have been consumed, the electrochemical reactions stop producing electricity.
- A secondary cell, on the other hand, can be recharged using battery charges to regenerate chemical reactions.
- A common dry cell is the zinc-carbon cell (dry Leclanché cell) has a nominal voltage of 1.5 volts, which is the same as an alkaline cell.
