SUMMARY
A strong lightning bolt transfers approximately 25 coulombs (C) of charge to Earth. The calculation for the number of electrons transferred is based on the charge of a single electron, which is 1.60 x 10-19 coulombs. Dividing 25 C by 1.60 x 10-19 C/electron yields 1.5625 x 1020 electrons. The discrepancy with the teacher's answer of 1.6 x 1020 electrons is attributed to a potential calculator entry error.
