This document provides information about various electrical concepts including: - Electricity is the flow of electrons from one point to another. There are two types - static and dynamic. - Current is the flow of electrons through a conductor. Voltage and resistance determine current based on Ohm's Law. - Common instruments used to measure electrical values are multimeters, oscilloscopes, function generators, and breadboards. - Capacitors store electric charge and react differently in DC versus AC circuits. Inductors oppose changes in current and produce self-induced voltages.
