بیشتر بخوانیدElectrical energy can be converted to light energy in a number of ways. One common way is through the use of incandescent bulbs. In an incandescent bulb, electrical current passes through a thin wire filament, heating it until it glows. The heat produces light, which escapes from the bulb and casts light on whatever is nearby.
