EE 2950 Chapter : Basic Concepts
Document Summary
Charge: charge is a fundamental characteristic of electrons and protons. Charge is designated by the symbol q and is measured in units of coulombs (c). The negative charge carried by a single individual electron is very small fraction of a coulomb). This is the smallest unit of charge that exists. Conductors: conductors are materials through which charge can easily move under the influence of an electric field. In this course we will use the concept of ideal conductors. This means that the conductors (wires) that we use in all of our circuits will be assumed to have zero resistance to charge flow. Current: current is a measure of how much charge is moved per unit of time. The unit of measure is the ampere (a). One ampere is defined as the transfer of one coulomb in one second. Voltage potential: voltage potential is a measure of the potential energy per unit charge.
