Heating effect of current is used in a bulb as the current heats up its filament and leads to the emission of the light due to burning of filament.
What are the effects of electric current?
The three effects of electric current are: 1. Heating effect 2. Magnetic effect 3. Chemical effect.
- Heating effect.
- Magnetic effect.
- Chemical effect. Answer verified by Toppr. Related questions. In charging a battery of motor-car, which of the following effect of electric current is used?
Which effect of current make a bulb glow?
Therefore, the effect of current responsible for the glow of the bulb in an electric circuit is the heating effect. So, the correct answer is “Option B”. Note: Due to the moving electrons in the filament of the bulb, a magnetic field is also produced resulting in some magnetic effects.

How is heating effect of electric current is used in electric bulbs to produce light?
Electric bulb works on the principle of heating effect of electric current. When electric current passes through a very thin, high resistance tungsten filament of an electric bulb, the filament becomes white hot and emits light.
What are 3 effects of electric current?
Hence, the three effects of electric current are heating effect, magnetic effect and chemical effect.
What are the five effects of electric current?
The main effects are heating, chemical and magnetic effects. When current flows in a circuit it exhibits various effects. The main effects are heating, chemical and magnetic effects.

What are the three main effects of an electric current?
When an electric current flows in a circuit it can have one or more of the following three effects: heating, magnetic or chemical.
Does the bulb glow?
The filament of an electric bulb glows because of the heating effect of electric current. As the current passes through the bulb it heats the filament which gives off light. … The filament then heats up and becomes red-hot as a result of this it begins to glow, turning electrical energy into light energy.
Why is the current in the circuit weak?
Why is the current in the circuit weak? Liquids like water (mineral water, or water with impurities), acids, bases, salts, etc offers high resistance to current than metal conductors. So, after passing through conducting liquids the current in the circuit becomes weak.
Why is the current in the circuit weak in some solution?
Liquids like water (mineral water, or water with impurities), acids, bases, salts etc offers high resistance to current than metal conductors. … So, after passing through conducting liquids the current in the circuit becomes weak.
Is used in electric bulbs?
Incandescent light bulbs consist of an air-tight glass enclosure (the envelope, or bulb) with a filament of tungsten wire inside the bulb, through which an electric current is passed.
Do light bulbs use AC or DC?
For light bulbs and heating elements, both AC and DC will work as long but the fact is that though all electric devices require direct current, alternating current is what is used to deliver electricity with the help of transformers which convert AC to DC for the use of electric devices.
Do fluorescent lights use AC or DC?
Fluorescent tubes are almost always powered with AC, but this circuit uses DC. Basically, this circuit is a voltage doubler composed by two 1N4007 diodes and two high voltage electrolytic capacitors of 10 μF 350 V. Such capacitors can be easily salvaged from compact fluorescent lamps.
