Question

Solve the example 1.2

Answer 1

Answer:

1e=1.6 ×10^-19C

1C=1/1.6×10^-19 e=6.25×10^18e

time required to get total charge of 1C=

=1C/(charge move out per second)

=6.25×10^18/10^9

=6.25×10^9 seconds

Answer 2

Answer:

The time required for total charge of 1C on other body is 198 years

Explanation:

Coulomb is the international system of units of electric charge that is directly proportional to the charge amount passed by a current of 1 ampere in 1 second.

$10^{9}$ Electron takes $1 sec$

1 electrons =$\frac{1}{10^{9} } sec$

$1C =6.242*10^{18} \\\\6.242*10^{18} takes \frac {6.242*10^{18}} {10^{9} } \\\\{6.242*10^{9} sec\\ \\\\\frac{{6.242*10^{9} } }{60*60*24*365} years\\\\=197.93 years\\\\=198 years$

Hence, it will take us almost 200 years to recover an one coulomb of charge from a body from which $10^{9}$ electrons escape per second. Hence, one coulomb is a fairly significant unit for many actual applications. But, it is equally critical to the understand roughly how many electrons make up a cubic centimetre of a substance. A copper cube with a side of 1 cm contains roughly $2.5 * 10^{24}$ electrons.
