Charge of one electron= 1.6×10^-19 C Charge of 10^9 electrons = 1.6×10^-19 C × 10^9 = 1.6×10^-10 C We can say,1.6×10^−10 C of charge move out of the body to another body every second. The time required to get a total charge of 1C = 1sec/1.6×10^-10 C = 6.25×10^9 / 365×24×3600 = 197.8 years or approximately 198 years.

Charge of one electron= 1.6×10^-19 C

Charge of 10^9 electrons = 1.6×10^-19 C × 10^9

= 1.6×10^-10 C

We can say,1.6×10^−10 C of charge move out of the body to another body every second.

The time required to get a total charge of

1C = 1sec/1.6×10^-10 C

= 6.25×10^9 / 365×24×3600

= 197.8 years or approximately 198 years.
