The light bulb transfers electrical energy into light. What is one type of energy that is also generated that is NOT a desired e
zimovet [89]

The old style (incandescent) light bulb converts more energy
into heat than it does into light.  If you're using it mainly as a
source of light, then it's a bummer, and its efficiency is very low. 
BUT ... if you're using an incandescent light bulb as a heater, then
its efficiency is much better.  It all depends on your point of view.

Why is the overall charge of the atom neutral or zero?
MrRissso [65]

Answer:

B

Explanation:

this is because the neutrons do not have a charge, the things that have charge in an atom are electrons and protons.

and in the nucleus of an atom, there are protons and neutrons so you can see that A is not the answer

if you see the periodic table, you will know that the number of electrons and protons are equal, so the charges cancel each other out, hence the charge of an atom will be neutral

let me give you a tip which I got from my teacher, never write there is no charge in the atom, this suggests that there is no protons or electrons.

instead, write, the it is neutral

hope it helps if not please report it so that someone else gets to try it out
