Lightning bolt electrons problem

Click For Summary
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.

PREREQUISITES
  • Understanding of electric charge and coulombs
  • Basic knowledge of electron charge (1.60 x 10-19 C)
  • Familiarity with scientific notation and exponent rules
  • Calculator proficiency for scientific calculations
NEXT STEPS
  • Review the principles of electric charge and its measurement in coulombs
  • Learn about the relationship between charge and the number of electrons
  • Practice scientific notation and calculations involving exponents
  • Explore common calculator functions for scientific calculations
USEFUL FOR

Students studying physics, educators teaching electric charge concepts, and anyone interested in understanding the fundamentals of electricity and electron transfer.

A strong lightning bolt transfers about 25 C to Earth. How many electrons are transferred?

1 electrons = 1.60E-19

so.. 25 / 1.60 E -19 = 1.5625E-18 electrons

but the answer that my teacher gave us is 1.6 E 20 electrons

what did i do wrong?
