Introduction to Electricity Symbol: (q) Unit:Coulomb (C) The fundamental electric quantity is charge. Atoms are composed of charge carrying particles: electronsand protons, and neutral particles, neutrons. The smallest amount of charge that exists is carried by an electron and a proton. Charge in an electron:qe= C Charge in a proton:qp= CChargeCurrent Current moves through a circuit element through variable. Current is rate of flow of negatively-charged particles, called electrons, through a predetermined cross-sectional area in a conductor. Like water flow. Essentially, flow of electrons in an electric circuit leads to the establishment of (t) =oq : relatively charged electrons (C)oAmp = C/secoOften measured in milliamps, mAdqdt Symbol: I Unit:AmpereCurrent-Water AnalogyVoltage Potential difference across two terminals in a circuit across variable. In order to move charge from point A to point B, work needs to be done.
•A resistor is a dissipative element. It converts electrical energy into heat energy. It is analogous to the viscous friction element of mechanical system.
