In order to understand how DC generators produce electricity, it is crucial to understand how the relative motion of a conductor moving through a magnetic field ( B ) induces forces that put the conductor’s electrons into motion; however, prior to engaging in a discussion about electromagnetic induction, we must briefly re-examine how the magneticContinue reading “INTRODUCTION TO ELECTRONICS: DC Generator Fundamentals”

ENERGY AND MOMENTUM: Stacked Ball Drop, Impulse, and the Galilean Transformation
Q: Three balls of mass m1, m2, and m3 fall together towards the earth. They accelerate until impact, and once the three-ball system collides elastically with the earth’s surface, the balls within the system approach one another with an instantaneous velocity ( v ). The momentum ( p = mv ) = ( m1 +Continue reading “ENERGY AND MOMENTUM: Stacked Ball Drop, Impulse, and the Galilean Transformation”
