In an electric bulb, light is produced due to the glowing of
$(a)$. the glass case of the bulb
$(b)$. the thin filament
$(c)$. the thick wires supporting the filament
$(d)$. gases inside glass case of the bulb.

Academic Physics NCERT Class 6

When the current is passed through an electric bulb, the filament of the bulb glows and the bulb produces light.
So, option $(b)$ is correct.

Filament of a torch bulb is$(a)$. a metal case$(b)$. metal tip at the centre of the base$(c)$. two thick wires$(d)$. a thin wire.
Though same current flows through the electric line wires and the bulb filament, yet only the filament of bulb glows. Give the reason behind it.
Why the filament of the bulb has a high melting point?
What is a filament of a bulb?
Which of the two is more energy efficient: filament type electric bulb or CFL? Why?
Who did the invention of the electric light bulb?
Consider the following material: Copper, tungsten, chromium, aluminium, nichrome, iron.Which of these is used to make(a) Heating element?(b) Filament of an electric bulb?
Paheli connected two bulbs to a cell as shown in the figure,She found that filament of bulb B is broken. Will bulb A glow in this circuit? Give reason."
Explain the important components and working of an electric bulb?
Electric bulb draws a current of $0.4\ ampere$. Calculate the amount of charge flowing through the bulb if the bulb glows for two hours also calculate the number of electrons passed.
Name the effect of current responsible for the glow of the bulb in an electric circuit.
Figure A and B, show a bulb connected to a cell in two different ways.$(i)$. What will be the direction of the current through the bulb in both the cases $(Q\ to\ P\ or\ P\ to\ Q)$?$(ii)$. Will the bulb glow in both cases?$(iii)$. Does the brightness of the glowing bulb depend on the direction of current through it?"
A small bulb is placed at the focal point of a converging lens. When the bulb is switched on, the lens produces:(a) a convergent beam of light (b) a pergent beam of light(c) a parallel beam of light (d) a patch of coloured light
In the circuit shown in the figure, when the switch is moved to the ’ON’ position,$(a)$. the bulb A will glow first$(b)$. the bulb B will glow first$(c)$. the bulb C will glow first$(d)$. all bulbs will glow together."
When we press the bulb of a dropper with its nozzle kept in water, the air in the dropper is seen to escape in the form of bubbles. Once we release the pressure on the bulb, water gets filled in the dropper. The rise of water in the dropper is due to:$(a)$. pressure of water.$(b)$. gravity of the earth.$(c)$. shape of rubber bulb.$(d)$. atmospheric pressure.
