What is electricity?

a form of energy and it comes from small particles called atoms

100
What is an insulator?
An insulator is an object that does not allow electricity to travel through it.
100
What is a proton?
A proton is a positively charged part of an atom.

what is a direct current (DC)?

the direct current is when electrons travel in one direction from the source of electricity to the device it is powering and back to the source. 

200

what are the different parts of an atom?

proton, neutron, electron and nucleus

What is a conductor?
A conductor is an object that allows electricity to pass through it.
200
What is an electron?
An electron is a negatively charged part of an atom.

what is altering current (AC)? 

an alternating current has electrons that travel back and forth very quickly creating a constant flow electricity.

what is a circuit?

the complete path that an electric current travels along

geothermal energy is...

energy that comes from the Earth.

500

which circuits have electrons that move back and forth, switching directions at a very fast pace

alternating current 

500

Name three insulators.

wood, rubber, most plastics

Why does your hair stand on end when you rub a ballon it it?

The atoms in your have lost electrons to the ballon through the rubbing and now your strands of hair have positive charges so they repel each other.
