The battery compartment also acts like a handle for holding the flashlight.
Though the flashlight is of a very simple design, it is a relatively new invention. It came into being after the incandescent light bulb and the dry cell was invented.
The name ?flashlight? has a humorous background. In the early days of the dry cell, the power of a dry cell battery was very limited. To save the dry cell from discharging quickly, the flashlight was operated intermittently and just long enough to check out the environments, hence the name ?flashlight?.
There are many flashlight designs available in the market today. Like dry cell flash lights, rechargeable acid type flashlights, rechargeable dry cell type, LED (Light Emitting Diode) type, solar charging type, electromagnet type, head lamp type, underwater type, rifle or gun light etc.
The dry cell flashlight is the simplest design and used in most households and consists of dry cells to power the electric bulb.
