SUMMARY

A battery-powered light bulb operates by allowing electrical current to flow through a filament, which heats up and emits light. The battery supplies the necessary current and voltage to facilitate this process. This fundamental principle of electrical flow is consistent across various types of light bulbs, including incandescent models. Understanding this mechanism is crucial for anyone interested in the functionality of battery-operated lighting solutions.
