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.
What else can I help you with?
When a torch is on what energy takes place?
When a torch is on, electrical energy is converted into light energy and heat energy. The electrical energy flows through the circuit of the torch, powering the light bulb to produce light and generating heat as a byproduct of the light production process.
What is the energy transformation in a torch?
In a torch, electrical energy from the batteries is converted into light energy and heat energy. The electrical energy powers the light bulb, which emits light energy. Some of the electrical energy is also converted into heat energy due to inefficiencies in the system.
Is torch both source of light and heat?
Yes, a torch can be a source of both light and heat. The light is produced by the flame or the electric bulb, while the heat is generated by the burning fuel or the electric components.
What is the energy conversion in torch battery?
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.
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.

What form of energy is stored in a torch?
light and heat

What happens to the energy in a torch once it is switched on?
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.
What type of energy does a portable torch have?
A portable torch typically contains chemical potential energy stored in the batteries or fuel used to power the light source. When the torch is turned on, this energy is converted into light energy and heat energy.
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 of these energy changes occurs when a battery operated torch is switched on?
Chemical energy becomes light and heat energy.
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.
Which type energy other than light energy is produced by incandescent light?
heat energy
