Why Does A Light Bulb Light Up Immediately at Sophia Debra blog

Why Does A Light Bulb Light Up Immediately. When a light bulb connects to an electrical power supply, an electrical current flows from one metal contact to the other. The answer is deceptively easy: The rate of flow of electrons is known as current. That's why the light bulb lights up almost instantly. The voltage wave (analogous to the pressure wave) travels along the wire at somewhere between a tenth and a half of the speed of light depending on the type of wire, and reaches the light bulb. This means that the electric current flowing through the filament heats it to the level where it starts emitting photons. Why do light bulbs get hot? One important point to consider here is that the filament of the light bulbs burns itself to produce light. This means that the average frequency of the light being emitted shifts toward the blue end of the spectrum as the object heats up, but it’s not. As the current travels through the wires and the filament, the. Current propagates at the speed of light. When we switch on a light bulb, then it lights immediately. If drift velocity of electrons is.
