ELECTRICITY FUNDAMENTALS Electricity is an apparent force in nature that exists whenever there is a net electrical charge between any two objects. Basics of Electrostatics: Electrical charges are either negative (electrons) or positive (protons) The unit of charge, q , is called the coloumb. When there are equal numbers of positive and negative charges there is no electrical force as there is no net charge. This is the case for a neutral atom. Electrical force is created when electrons are transferred from one material to another (e.g. rubbing a wool cloth with a plastic comb). Electrical charge is conserved; charge is neither created nor destroyed Properties of Electricity: CURRENT: denoted by I and measured in amperes. Current flows from negatively charged material to positively charged material and is essentially the number of electrons per second that are carried through a conductor. Current is measured in units of amps. 1 amp = 1 coloumb/sec ...
