When a torch is switched on energy is transferred from the battery to the bulb how is energy?
When a torch is switched on, the electrical energy stored in the battery is converted into light and heat energy by the bulb. The electrical energy flows through the circuit and causes the bulb’s filament to heat up, emitting light as a result of this process.
What energy changes take place in a torch?
In a torch, chemical energy stored in the battery is converted into electrical energy when the torch is turned on. The electrical energy is then converted into light and heat energy when the current passes through the bulb's filament, producing the light that is emitted from the torch.
What parts of the torch are the insulator and the conductor?
The handle of the torch is typically the insulator, as it is made of non-conductive materials like plastic or rubber to prevent electric shocks. The filament or bulb inside the torch serves as the conductor, allowing electricity to pass through and produce light.
What is the filament in a light bulb made of?
The filament in a light bulb is typically made of tungsten.
What energy conversion take place when using a torch?
When using a torch, electrical energy is converted into thermal energy and light energy. The electrical energy is used to heat a filament inside the bulb, which then produces both heat and light.
Which is more powerful a torch bulb or a mains filament lamp?
Mains filament

What is filament in a bulb?
The filament is the small coil that glows when the bulb is on. I believe its made out of tungsten
What is the filament in a light bulb made of?
The filament in a light bulb is typically made of tungsten.
What is filament shaped into?
Bulb's filament are wounded into a coil.
Will the bulb light if the filament is broken Why?
No, the bulb will not light if the filament is broken because the filament is the part of the bulb that creates light when electricity passes through it. Without a functioning filament, there is no source of light in the bulb.
What energy conversion take place when using a torch?
When using a torch, electrical energy is converted into thermal energy and light energy. The electrical energy is used to heat a filament inside the bulb, which then produces both heat and light.
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A high-resistance bulb typically has a thicker filament compared to a low-resistance bulb. The thicker filament in a high-resistance bulb can withstand the greater heat generated by the increased resistance, resulting in a longer lifespan for the bulb.
How is energy transferred from the battery to the bulb of a torch or flashlight?
Energy is transferred from the battery to the bulb of a torch or flashlight through a closed circuit. When the battery is connected to the bulb, it provides electrical energy to the filament in the bulb, which then converts the electrical energy into light energy through the process of electrical resistance. This light energy is what produces the glow in the bulb.
