Energy is transferred to a light bulb when an electric current flows through a filament in the bulb, heating it up and causing it to emit light. The electrical energy is converted into light and heat energy by the filament, which produces the visible light that we see.

What type of energy transformation occurs when a light bulb is on?
Electrical energy is transferred into light energy, however if the light bulb is an older one, some energy will also be transferred into heat loss.
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.
What forms of energy are tranferred from battery to light bulb?
The forms of energy transferred from a battery to a light bulb are chemical energy (stored in the battery) being converted to electrical energy (flowing through the wires) and then to light energy and heat energy (produced by the light bulb).
What wasted energy is transferred from the bulb to its surroundings?
Wasted energy in the form of heat is transferred from the bulb to its surroundings. This is because light bulbs are not 100% efficient at converting electrical energy into light energy, so some energy is lost as heat during the process.
What are the steps to trsnsfer energy when you turn on a light?
When you turn on a light, electrical energy from the power source is transferred through the wires to the light bulb. The electrical energy is then converted into light energy and heat energy by the filament in the bulb, illuminating the surroundings.

How is energy transfered in a simple system?
In a simple system, such as a light bulb connected to a battery, energy is transferred through electrical currents. When the battery is connected to the light bulb, it provides the energy needed for the bulb to emit light. This energy transfer occurs as the electrons flow through the wire from the battery to the light bulb.
Can energy be transferred from one store to another?
Yes, energy can be transferred from one energy store to another through various processes such as conduction, convection, and radiation. For example, electrical energy can be transferred to light energy in a light bulb, or chemical energy can be transformed into kinetic energy in a moving car.
What is the energy transfer in a bulb?
In a bulb, electrical energy is transferred into light energy and heat energy. When the bulb is turned on, the electrical current flows through the filament, causing it to heat up and emit light. Some of the electrical energy is also converted into heat energy due to resistance in the filament.
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 transfers in a light bulb?
In a light bulb, electrical energy is transferred into light energy and heat energy. The electrical energy flows through the filament, causing it to heat up and emit light due to incandescence. Some of the electrical energy is also converted into heat energy that is emitted as infrared radiation.
What is the main pathway by which energy is wastefully transferred from a light bulb?
Energy is wastefully transferred from a light bulb primarily through heat generation. When electricity passes through the filament in an incandescent light bulb, it heats up and emits light, but a significant portion of the energy is also released as heat, making these bulbs less energy-efficient compared to LED bulbs that convert more energy into visible light.
