If `10^(9)` electrons move out of a body to another body every second, then the time required to get a total charge of 1 C on the other body is

Explanation

In one second `10^(9)` electrons move out of the body therefore the charge given out in one seconds is `1.6 xx10^(-19) xx 10^(9) C=1.6 xx10^(-10) C` the time required to accumulate a charge of 1 c can then be estimeated to be from a body from which `10^(9)` elelctons move out every second we will unit for many practical purposes it is however also important to know what is roughtly the number of a cubic piece of coper of side 1 cm contains about `2.5 xx10^(24)` electrons
