The relationship between cause, effect, and resistance ( R ) to change are beautifully summed up by the Ohm’s law equation: ( V / R ) = I The greater the ability a system has to resist change, the less so that change will be observed. As far as Ohm’s law is concerned, change isContinue reading “INTRODUCTION TO ELECTRONICS: The Magnetomotive Force”

INTRODUCTION TO ELECTRONICS: Permanent Magnets, Contact Switches, and Hall Effect Sensors
Prior to engaging in studies of electromagnetic devices, an examination of simple yet very important devices made of permanent magnets is due. In the diagram below, a magnet is used to control a switch that regulates the flow of electricity in a circuit: In order to close the circuit and elicit flow of electric currentContinue reading “INTRODUCTION TO ELECTRONICS: Permanent Magnets, Contact Switches, and Hall Effect Sensors“
