Page 2 Series and Parallel circuits TABLE OF CONTENTS I N T R O D U C T I O N This laboratory exercise was designed to familiarize one with series and parallel circuits and be able to identify the three important components of a circuit and the fundamental relationships between the quantitative electrical values of resistance (R), voltage (V) and current (I) as defined by Georg Ohm which in turn this relationship was named after himself in units of Ohm (...
