Comparing shocks from static electricity and electric currents is like comparing apples and oranges, they are similar but quite different at the same time.. Every year many people are injured and sometimes killed from electrocution as even small amounts of electric current can be lethal. . BY HEI MAN KWOK 12N03S . 5.1 electric potential difference, current and resistance. Model of electric conduction in a metal – energy transfer . Charge carriers have kinetic energy . These collide with lattice ions . A . force. is a push or pull exerted on an object.. Energy. is the ability to do work or cause change.. Potential energy . is the stored energy that results from the position or shape of an object.. . 21-6 The . Electric . Field. Gravitational . Field. +. -e. Electric Field. +. +. +. Units .

If two charges are opposite, what happens to those charges?. 4. The force between two charges can be calculated using the following equation . December 9. th. , 2011. Electric Current is the measure of the . rate of electron flow past a given point in a circuit. ; measured in amperes (A). . Think of it in terms of a waterfall. If you could count the number of water molecules that drop over the edge every second, you could get the rate at which water is flowing past a particular point. . Electric Current Notes. Key Terms. Voltage . produces a flow of charge, or . current. , within a conductor. . The . flow is restrained by the . resistance . it encounters. . The . rate at which energy is transferred by electric current is . 6.1 Electric Charge. Positive and Negative Charges. Matter is composed of . _______. Atoms are composed of . protons. , . neutrons. and . electrons. The amount of positive charge on a proton is . _____ . Electric Current:. RECALL: In static electricity, an electric charge . stays . in one area. . In current electricity an electric charge moves through conductors along a path. Its . electrons. that move NOT . Comparing shocks from static electricity and electric currents is like comparing apples and oranges, they are similar but quite different at the same time..
