∙ 11y agoWhen 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.
When a torch is switched on, the electrical energy from the battery is converted to light energy and heat energy. The electrical energy powers the light source (such as LEDs or a bulb) to produce light, and a small portion of the energy is also dissipated as heat.
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.
A wind-up torch typically works by converting mechanical energy from winding a crank into electrical energy that powers the light. This energy is stored in a rechargeable battery within the torch. When the torch is wound up, the mechanical energy is transferred to the battery, which then powers the light emitting diodes (LEDs) to produce light.
In a torch battery, chemical energy is converted to electrical energy when the battery is connected to the circuit in the torch. The electrical energy then powers the light bulb, converting the electrical energy into light energy and heat energy.
The energy in a torch battery is stored chemically in the form of chemical potential energy. When the battery is connected in a circuit, a chemical reaction occurs within the battery, releasing this stored energy in the form of electrical energy that powers the torch.
Chemical energy becomes light and heat energy.

Energy is transferred in a torch from the battery to the bulb primarily by electricity. The battery provides an electrical current that flows through the circuit inside the torch, ultimately powering the bulb to produce light. Some energy may be lost as thermal energy due to resistance in the circuit, but the main transfer mechanism is through electricity.

potential energy
powers the torch to give it energy
A battery-powered torch converts chemical energy stored in the battery into electrical energy, which is then converted into light energy when the circuit is completed and the bulb is illuminated.
Energy in a torch is stored primarily in its battery or power source. When you switch the torch on, the battery converts stored chemical energy into electrical energy, which powers the light bulb or LED to produce light.
Energy is transferred from the torch to the surroundings through heat radiation. As the torch emits light and heat, some of this energy is absorbed by the surrounding objects and the air, causing an increase in their temperature. Heat can also be transferred through conduction and convection as the hot air rises and spreads out.
