Why are dry cells commonly used in portable devices like torches?

Verified Answer

Dry cells are widely used in portable devices such as torches because they are compact, safe, and easy to handle, making them ideal for mobile applications.

Key reasons for their use:

  1. Portable and lightweight
    Dry cells are small in size and easy to carry, which makes them suitable for handheld devices.
  2. No liquid leakage
    Unlike wet cells, dry cells use a paste electrolyte, reducing the risk of leakage and making them safer to use in any position.
  3. Simple and convenient design
    They are easy to install, replace, and require no maintenance.
  4. Reliable power supply
    Dry cells provide a steady and sufficient amount of voltage for low-power devices like torches, remote controls, and clocks.
  5. Cost-effective
    They are affordable and easily available in the market.
  6. Long shelf life
    Dry cells can be stored for a long time without significant loss of charge.

In simple terms:
Dry cells are preferred in portable devices because they are safe, compact, and provide reliable power without leakage.
