Electrical, provided either by batteries, mains power, dynamo or stored solar energy. It is more properly described as electro-kinetic energy, as electricity requires the movement of electrons along a constant catalytic medium to provide 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.
potential energy
A torch typically uses chemical energy stored in batteries to produce light. The batteries in the torch provide electrical energy that powers the light bulb or LED to produce the illumination.
Energy in a torch is typically stored in a battery as chemical energy. When the torch is turned on, the chemical energy is converted into electrical energy, which powers the light bulb or LED in the torch, producing light.
Yes. The heat and light energy in a torch are separate. From the total energy input to the torch (chemical energy from batteries), Some is useful (the light energy) and some is wasted. (heat/thermal energy) The more efficient an appliance is ,the less energy out of the input energy is wasted. For example, an appliance may be 70% efficient. If it is supplied with 100J (joules) of energy, 70J will be useful and 30J will be wasted. Along with light energy, heat energy is also produced by a torch and is wasted. Heat energy is the most common form of wasted energy in appliances. Other appliances will waste energy in the form of heat, though it may not always be obvious.

The load in a torch is tehb thin tungsten wire in the bottom of the torch. It converts electrical energy into light energy.

We run out of means to convert it. Coal is stored potential energy, if we use it all and the resulting heat energy escapes into space, we've lost that energy. World's water evaporates, no hydro power.
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.
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 input (In) of a torch refers to the amount of electrical energy supplied to it, typically measured in watts or joules. This energy is converted into light and heat when the torch is powered on. The efficiency of this conversion can vary based on the type of bulb used (e.g., incandescent, LED) and the power source. For example, a standard LED torch might use around 3 to 5 watts, while a high-powered torch could consume significantly more.
