Question

plz ans me in detail as soon as possible​

Answer 1

Answer:

So here is ur ans...

Given: no.of electrons= 1.2*10^20 electrons

Time in which the electrons pass through conductor=2 min.= 2*60 sec.=120 sec.

current=?

solution:-

1 coulomb= 1.6*10^-19 electrons

so firstly we will change the no.of electrons into coulomb

so,1.2 *10^20 electrons are given.

therefore 1 coulomb= 1.2*10^20*1.6*10^-19

1.2*1.6*10^20+-19=1.2*1.6*10

Current (I)=charge(q)/time(t)

=1.2*1.6*10/120

=12*16/12

16A

Therefore,current = 16 A

follow me..if u wish nd i think u like the way i understand...
