all windup watches work by a mainspring that is wound up really tight, the spring wants to let go as soon as it is wound up tight. as you wind up the mainspring that parts in the watch start to move and the watch starts to keeps time. this is called a balance action. the balance wheel has a hairspring under it that returns the balance wheel to its main position as you wind the mainspring the force of it puts tension on the parts and that is how the windup watch works.
It work's by putting wind in-to it.
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
Things that need a battery in order to work, must need Direct Current at some point, if not all, for it to work. eg a hand torch.
Mechanical, civil, electrical, environmental and industrial engineers all work on offshore wind.
It depends on where you live. Solar panels work well in desert areas. While wind turbines work best near large lakes, oceans, or mountains. Wind turbines need to be very high up and solar panels need to face the sun as it moves across the sky.
A wind-up torch typically works by converting mechanical energy from winding a crank into electrical energy that powers the light. This energy is stored in a rechargeable battery within the torch. When the torch is wound up, the mechanical energy is transferred to the battery, which then powers the light emitting diodes (LEDs) to produce light.

A wind-up torch is a flashlight that is powered by winding a crank or handle to generate electricity, rather than relying on batteries. This makes it a convenient and eco-friendly option for emergency situations or outdoor activities.
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.
my torch does work though...
There are two different meaning of the word 'wind'. One can be like the wind in the air, but the other can be as in 'to wind up a torch' or annoying someone. Here are three sentences for each: "The wind carries tiny things because it is powerful." "The wind is very strong today so be careful your paper doesn't blow away." "The wind annoys me because it messes up my hair." "James likes to wind up his brother." (James likes to annoy his brother.) "I have to wind my torch up every five minutes." "Wind down the window so that I can speak to that other driver."
A wind-up torch is a type of flashlight that is powered by manually winding a crank or handle to generate energy to light up the bulb. It does not require batteries or external power sources, making it useful in emergency situations or outdoor activities.
It provides the light in the torch
Are you serious????
The wind can blow in any direction.
aha you guys got no clue lol youll never find this answer or at least get it from mwa
Energy can be wasted in a wind-up torch when excessive force is used to crank the handle, generating more energy than needed to power the torch. This leads to inefficiencies as the extra energy is not utilized effectively. Additionally, friction in the mechanical components can cause energy loss as heat, further reducing the overall efficiency of the torch.
