Abstract:
This research discussed air ionization under different conditions due of the effect of air condition or fan together or separately. The experiments had conduct in solid state physics lab at Sudan university of science and technology. It was found that ionization potential is small when both air condition and fan operate compared to that when they are not operate .This indicates that air condition and fan ionizes air with different opposite charges. The ionization potential is found to be greater when air condition operate alone or the fan operate alone, which confirms the belief that they increases air ionization.
