Answer: When electric current passes through a thin, high resistance tungsten filament of an electric bulb, the filament becomes hot and emits light. This is the heating effect of electric current.
Which effect is used in electric heater?
The heating effect of current is used in various electrical heating appliances such as electric bulb, electric iron, room heaters, geysers, electric fuse etc.
Which effect of electric current is used when a bulb is glowing?
Heating effect can be used for testing the conductivity of a liquid The heating effect of current is responsible for the glowing of the bulb. When current passes through the bulb, the filament gets heated to a high temperature and as a result bulb starts glowing.
What does electric current effect?
Hence, the three effects of electric current are heating effect, magnetic effect and chemical effect.
Which effect of electric current is Utilised?
The heating effect of current is utilised in the working of an electric fuse.
What is effect of electric current on neon lamp?
Like other gas discharge lamps, the neon lamp has negative resistance; its voltage falls with increasing current after the lamp reaches its breakdown voltage. Therefore, the lamp has hysteresis; its turn-off (extinction) voltage is lower than its turn-on (breakdown) voltage.
Which effect of electric current is Utilised I in an electric iron II in an electric bulb?
Answer: Heating effect is the effect that is used in electric iron .
What are the two main effects of current?
When current flows in a circuit it exhibits various effects. The main effects are heating, chemical and magnetic effects.
Which effect of electric current is Utilised in electric crane?
Answer: Magnatic effect of electric current is used in cranes……
Which effect of electric current is Utilised in making electromagnet?
The magnetic effect of electric current is widely utilized in making electromagnets.
Which effect of electric current is Utilised in the working of an electric fuse What is the function of an electric fuse?
The fuse works on the principle of heating effect of electric current. Normally current flows through the fuse without undue heating. But if too much current passes through it, the fuse melts and breaks the circuit, thus stopping the current which could cause a fire if it was not stopped.
