Unlike phantom power, bias does not require a balanced circuit. Bias supplies power to a Junction Field Effect Transistor (JFET) connected to the output of an electret condenser mic element. The JFET acts as an impedance converter that is a necessity in any microphone design that uses a condenser element.
Iodine atoms have 53 electrons and the shell structure is 2.8.18.18.7. The ground state electron configuration of ground state gaseous neutral iodine is [Kr].4d10.5s2.5p5 and the term symbol is 2P3/2.
Therefore the Potassium electron configuration will be 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1. Video: Potassium Electron Configuration Notation. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.
