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.
Valence electrons - the electrons located at the outermost shell of an atom . Electron configuration - the arrangement of electrons around the nucleus of an atom . Spdf notation - a short, easy format for notating electron configuration using the periodic table and subshells s, p, d, and f.
