If a torch was not working what sort of things would be wrong with it?

If a torch is not working, it could be due to a dead battery, which is the most common issue. Other possible problems include a faulty bulb, a broken connection in the wiring, or corrosion in the battery compartment. Additionally, the switch may be malfunctioning or stuck, preventing the torch from turning on. Lastly, physical damage to the casing could also affect its functionality.
