If 10^(9) electronsmove outof a body to another body every second how much time is requiredto get a total charge of 1 C on the otherbody |
| Answer» Solution :In onesecond`10^(9)` electrons move outof the BODY thereforethe 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 1ccan thenbe estimeated to befrom a body from which `10^(9)`elelctons move out every second we will unit for many practical purposes it ishowever also importantto know what is roughtly the number of a cubic piece of coper of SIDE 1 CM contains about`2.5 xx10^(24)`electrons | |
