The number of excess electrons contained within the drop of Millikan oil drop experiment is determined as 7 excess electrons.
The excess electrons contained within the drop of Millikan oil drop experiment is calculated as follows;
-1.60 x 10⁻¹⁹ C = 1 electron
-1.12×10⁻¹⁸ C = ? electrons
= ( -1.12×10⁻¹⁸ C) / (-1.60 x 10⁻¹⁹ C )
= 7 excess electrons
Thus, the number of excess electrons contained within the drop of Millikan oil drop experiment is determined as 7 excess electrons.
