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.
Electron configuration[edit] Electron configurations of the neutral gaseous atoms in the ground state. Given by subshells in concise form, by subshells written out, and by number of electrons per shell. Electron configurations of elements beyond nobelium (element 102) are tentative and those beyond rutherfordium (element 104) are predicted.
