Objective of the lectures is to support the lab. We’ll need some understanding of electrical fundamentals to do the lab exercises. Electric Circuit Consists of: Energy or Power Source: Battery, Lab Power Supply Conductors: Metal members that we use to connect various electric circuit elements. Resistors: Conductors that resist the flow of electrical current. Electrical Fundamentals

Devices that have very low resistance to the flow of current we call conductors. Devices that have very high resistance to the flow of current we call insulators. The units of resistance are Ohms ( Ω. ) Electrons: The charge carrier responsible (in most cases) for the flow of current. Units of charge are Coulombs (C.) Current: The net amount of charge that flows in one second in a given direction past a point in a conductor. Electrical Fundamentals
