He is best known for two (*) rules, one of which states that the total potential change over an entire circuit is zero, and the other of which states that the sum of all currents entering a junction equals the sum of all currents leaving it.
A solid, liquid, or dense gas produces a spectrum of all wavelengths according to the first of this man's Three Laws of Spectroscopy. Those laws were discovered by this man and Robert Bunsen, with whom he discovered cesium and rubidium. He is best known for two (*) rules, one of which states that the total potential change over an entire circuit is zero, and the other of which states that the sum of all currents entering a junction equals the sum of all currents leaving it. For 10 points, name this German physicist with namesake Loop and Junction Rules.
