What are electrons?
Very small particles that travel around an electrical circuit.
Does atoms conducts charges? and what are those.
yes, of course it conducts electricity. and they are positive, negative, neutral.
How is energy transformation is done?
the change from one from of energy to another, e.g., electrical energy to heat energy in a toaster.
What object does not conduct electricity the most?
rubber
Why do conductors conduct electricity well?
A material containing many autonomous electrons that move freely without being bound by the atomic nucleus.
What makes electricity? (3 things).
Hydro dam, wind power generation, solar power generation..........
What is mass number?
The mass number is the total number of protons and neutrons in a nucleus.
What is energy chain?
the movement of energy through a system.
Why do insulators not conduct electricity?
The electrons in the insulators are tightly bound to the atoms and cannot move freely.
What materials are mainly used to make wires intended to transport electricity?
silver, copper.
What is resistance?
The difficulty that the electric current has when flowing around a circuit.
Can you name all the parts of an atom?
electrons, protons, neutrons, nucleus and orbits.
what is the unit of the energy?
a unit of electrical power. one watt is equal to one joule of energy in one second.
Are people insulators?
That's right! Because humans can easily get electrocuted.
Which metal has the highest electrical conductivity?
silver!
