what kind of energy is being used when the light bulb lights up? mechanical , thermal , chemical , electrical ?

OpenStudy (anonymous):

help please someone ?

OpenStudy (zale101):

Chemical energy is when substances are released due to chemical reaction Mechanical Energy is energy caused due to its motion can also act as a kinetic -typically an object that is moving has a mechanical energy Electric energy is done when a electric charge flows into a conductor Thermal energy is the potential energy made through temperature-also a total of kinetic energy Now, what do you think?

OpenStudy (anonymous):

im thinking mechanical ???

OpenStudy (zale101):

why? Hint: How are light bulbs get lightened?

OpenStudy (anonymous):

thermal energy and they get light by electricty

OpenStudy (zale101):

Does light bulbs just lightened by conducting heat from the sun?

OpenStudy (anonymous):

no by electricity ? correct ?

OpenStudy (anonymous):

so electrical

OpenStudy (zale101):

yeah, electricity makes the bulb to light

OpenStudy (zale101):

so it uses electrical energy

OpenStudy (zale101):

by the electrical contact of the bulb

OpenStudy (zale101):

if light bulb gets lightened by heat, then it uses thermal energy because temperature is playing a major role
