When a light switch is turned on, electrical energy from the power source is converted into light energy and heat energy by the light bulb. The electrical energy flows through the circuit, causing the filament in the bulb to glow and emit light while also producing heat as a byproduct.
Not much. The main role of a light switch is not to transform energy, but to allow energy to flow - or to stop it from flowing. Electrical energy'in this case.

Why wont your energy efficient light bulb power completely off when the light switch is turned off?
Energy efficient light bulbs may have residual energy stored in them even when the light switch is turned off due to capacitors and other components. This residual energy allows them to power on more quickly when the switch is turned back on. It is normal and does not indicate a malfunction.
Do light sockets without bulbs in them still use energy when their switch is turned on?
No, light sockets without bulbs do not consume energy when the switch is turned on because there is no electrical load present to draw electricity. The circuit remains open when there is no bulb, so no electricity flows through it.
When the flashlight is turned on what energy changes?
When a flashlight is turned on, electrical energy from the battery is converted into light energy and heat energy by the bulb. The chemical energy stored in the battery is transformed into electrical energy, and then into light and heat energy by the bulb to produce the illumination.
When a light switch is turned on what is done to the curcuit?
When a light switched is turned on the circuit is usually closed.
What 3 kinds of energy are involved when a light bulb is turned on?
When a light bulb is turned on, electrical energy is converted into light energy and heat energy. Electrical energy powers the flow of electrons through the filament, generating light energy and heat energy in the process.
Is a light switch potential energy?
No, a light switch is not potential energy by itself. It is a device that controls the flow of electricity to a light bulb, converting electrical energy into light energy when turned on.
What would you use to transfer electrical energy into light and sound energy?
you flip a light switch on and it is turned into light energy
When a light is turned on energy from electricity changes into?
gas
How do you describe the changes in energy in a light bulb?
When a light bulb is turned on, electrical energy is transformed into light (radiant) energy and heat energy. This conversion process results in changes in energy form but the total energy remains constant, following the law of conservation of energy.
Describe the way energy changes form when an electric light is turned on?
When an electric light is turned on, electrical energy is converted into light energy and heat energy. The electrical energy powers the light bulb, causing it to emit light. Some of the electrical energy is also transformed into heat energy due to the resistance within the light bulb.
What energy transformation occurs when a chandelier brightens a ballroom after a waiter moves a switch?
The electrical energy from the power source is transformed into light energy by the chandelier's bulbs when the switch is turned on, illuminating the ballroom.
What type of energy changes from one form to another when a light bulb is turned on?
first electrical,light,chemical,thermal
When a light switch is turned on what travels through the wire?
Current flows through a wire when a light switch is turned on.
What kind of energy transformation takes place when a chandelier brightens a room after a waiter moves a switch room?
The electrical energy from the mains is transformed into light and heat energy in the light bulbs of the chandelier when the switch is turned on, illuminating the room.
What happens when a lamp plugged into an electric outlet is turned on?
the form of energy changes and the total of energy increases
