potential energy is like when you wind up a torch or a radio
A light bulb uses electrical energy, and produces light, as well as heat.
No. The incandescent bulb uses electrical energy and the light stick uses chemical energy.
electric energy
A light bulb uses energy. It uses electricity.
It uses less energy to produce the same amount of illumination as a standard light bulb
A light bulb is not energy, but is a device that uses electrical energy to create electromagnetic energy in the form (in part) of visible light and heat.
No.it uses energy sources (electrical energy to light up
incandescent
No.it uses energy sources (electrical energy to light up
The light bulb uses electrical energy, and produces light, as well as waste heat. The act of turning it on in itself uses a small amount of energy stored in your muscles.
energy is energy It does not matter what you are using the energy for, it matters how much energy you are using A 200 watt light bulb uses more energy than a 100 watt light bulb A 200 watt motor uses more energy than a 100 watt light bulb A 200 watt heater uses more energy than a 100 watt light bulb
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
