Answer:
A dry cell uses a paste electrolyte, with only enough moisture to allow current to flow. Unlike a wet cell, a dry cell can operate in any orientation without spilling, as it contains no free liquid, making it suitable for portable equipment

- A dry cell is made out of a zinc container with a negative electrode on the bottom.
- The positive electrode is a carbon rod in the centre with a brass cover.
- This is encased in a muslin bag containing a combination of manganese dioxide and charcoal.
- A wet paste of ammonium chloride serves as the electrolyte.
- The zinc container's outside body is insulated with cardboard (save for the base).
- The chemical reaction that occurs in the dry cell causes current to flow in the circuit when it is linked to a circuit with a bulb.
- The bulb will glow as a result. A main cell, the dry cell cannot be recharged.
