Question

A current of 10 A flows for 1 hours through any cross section of a conductor. Find the amount of charge
and number of electrons flow through conductor.

Answer 1

the amount of charge is Q is equal to 36000 c.
$36000 \div 1.6 \times 10000000000000000000$

Answer 2

Answer:

A current of 10 A flows for 1 hour through any cross-section  of a conductor, the amount of charge  is  $36*10^{3}C$ and number of electrons flowing through a conductor is $22*10^{22}$

Explanation:

• The electric current is the division of charge flowing to time of passing the charges

• If (n) number of charged particles with charge (q) moving through a cross-section within a time (t), then

        current $I=nq/t$

From the question, we have

the current through the conductor $I=10A$

time of passing $t=1hr=3600s$

charge of an electron $q=1.6*10^{-19}C$

rearrange the terms to get the number of electrons

$n=It/q$

$n=\frac{10*3600}{1.6*10^{-19} } =22.5*10^{22}$

the amount of charge is the product of the charge of one electron and the number of electrons, that is

$Q=qn=1.6*10^{-19}*22.5*10^{22} =36*10^{3}C$
