The calculation involves determining the current (charge flow per unit time) and then using it to find the time required to accumulate a specific amount of charge. The conversion of seconds to years is a crucial step.
If $10^9$ electrones move out of a body to mother body every second how much time it requires to get a 1 coulomb charge on the other body? [Given that ; $1yr \approx 3 \times 10^7$ sec]
