Question

a silver wire of radius 0.1m carries a current of 2A .if charge density in silver is 5.86 then drift velocity is​

Answer 1

Answer:

Explanation:

1 hour 15 minutes=4500 seconds

i=q/t

i=90/4500=0.02 amperes

j=i/a

j=0.02/(3.14*0.05*0.05)

j=2.55*10^4 amp/m^2

drift velocity=j/ne

v(d)=2.55*10000/((5.28*10^22)*(1.6*10^-19)

v(d)=2.69*10^-7
