Reducing this waste is crucial for improving energy sustainability and lowering greenhouse gas emissions.

As the electric current flows through the filament of a light bulb, its resistance causes the filament to heat up. This increase in temperature leads to a greater emission of light, as the filament reaches higher energy states. The gradual increase in current allows the filament to heat up steadily, resulting in a smooth transition from dim to bright glow. If the current were to increase too quickly, it could damage the filament due to thermal stress.

A circuit breaker is a protective device that automatically interrupts the flow of electricity in the event of a fault, such as an overload or short circuit, to prevent damage to the electrical system.
