Question

the potential difference of 200v is maintained across a conductor of resistance 1000 ohm ,calculate the current through the conductor and number of electrons passing through it in one second​

Answer 1

Answer:

1.25×10^19

Explanation:

Number of electrons flowing per sec, through conductor is the ratio of total charge flowing to the charge ofan electron.

Here V = 200 volt; R = 100 ohm;

e=1.6*10^-19C

Now I=V/R=200/100=2 amphere

chart flowing in t

=1 sec, q=I t=2*1=2C

Therefore, number of Ω electrons flowing through the conductor flowing in 1 s,

n=q/e=2/1.6*10^-19=1.25*10^19
