Final answer:
Common problems with torch operations include overheating due to internal resistance leading to energy dissipation, significant battery drain from intensive power use, and malfunctioning switches from frequent use or poor manufacturing.
Step-by-step explanation:
Common problems that occur with torch operations include overheating, battery drain, and a malfunctioning switch. When a torch is being used, energy from the battery is converted into light and heat. However, some of this energy can also be dissipated as heat due to the internal resistance within the battery, which can lead to overheating. The process of driving the LED or bulb in a torch can be power-intensive, leading to significant battery drain if the torch is used regularly or for extended periods. Lastly, frequent use or poor manufacturing can lead to a malfunctioning switch, which may prevent the torch from turning on or off correctly.
