Lights Bulb
Why does a bulb light up instantly but a tubelight lights up after some time flickering ?

Because when an electric charge is passed through the tungsten filament it glows instantaneously. A fluorescent tube has no filament, just gas - usually argon - and an inner fluorescent coating. The gas has to get up to temperature before it can sustain a constant current and cause the coating to react with it and glow. This usually takes a few seconds and is the time when the light is using the most electric current.
