Unformatted text preview: epend on what your test charge is. No matter what, if a charge is free to move in an applied electric field, it will move in the direction that lowers its potential energy. Electric Potential Electric Potential Example An electron in the picture tube of an older TV set is accelerated from rest through a potential difference ΔV!=!5000V by a uniform electric field. What is the change in potential energy of the electron? What is the speed of the electron as a result of this acceleration (assume it started from rest)? Answer Draw a quick picture of the situation: E –v Since the electron moves in the opposite direction as the electric field, its electric potential will increase as a result of this motion. If this would have been a proton, then the electric potential would have decreased as a result of its motion. L...
