The wind-up torch was not invented by a single person, but rather developed over time by various scientists and engineers. However, early versions of hand-cranked flashlights or torches date back to the late 19th century. The wind-up mechanism allows users to generate power by manually turning a crank attached to a small generator within the device, eliminating the need for batteries.
Energy in a torch is typically stored in a battery as chemical energy. When the torch is turned on, the chemical energy is converted into electrical energy, which powers the light bulb or LED in the torch, producing light.
A torch typically emits around 15-100 lumens of light, depending on the type and brand of the torch.
No, a magnet should not stop a torch from working. Torches typically use batteries to power the light, and magnets do not interfere with the electrical circuit in a torch.
The load in a torch is tehb thin tungsten wire in the bottom of the torch. It converts electrical energy into light energy.
The dynamo torch was invented by Ming-Chih Wei. The dynamo torch is a flashlight that stores energy in a flywheel.
