Which devise changes electrical energy into light energy?
A light bulb changes electrical energy into light energy by heating a filament inside the bulb with electricity, causing it to emit light. LED (Light Emitting Diode) devices also convert electrical energy into light energy through a process called electroluminescence.
Which part of a circuit changes electrical energy into another form of energy?
A resistor or a component like a light bulb or a motor changes electrical energy into another form of energy, such as heat, light, or mechanical motion.
How does energy change in a flashlight?
Energy in a flashlight changes from stored chemical energy in the battery to electrical energy when the battery powers the light bulb, which then converts electrical energy into light and heat energy.
Whats a device that changes electrical energy into light energy?
An LED (light-emitting diode) is a common device that converts electrical energy into light energy. When an electric current is passed through the LED, it emits light.
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.
