It composes of a nucleus which is the central part, the protons and electrons. 12 Same as electricity or flow of electron. The amount of current flowing in a circuit can be measured in ampere (1) 13 The amount of pulling force that makes the electron flow. Also known as potential difference or EMF (electromotive force). The amount of voltage can be measured in volt Materials that easily allow the flow of current, or it has a low resistance to 16. (V). 14. current flow. 15. Materials that do not easily allow the flow of current, or it has a high resistance to current flow. Define as the flow of electron or electric current. It is an invisible form of energy that can be transform into other form of energy like heat light and mechanical 17. The negatively charge component of an atom. It has the ability to flow. 18. Define as the opposition to the flow of current. The amount of resistance can be measure in ohms (Q2). 19. The positively charge component of an atom. It has the ability to attract electron 20.
