Question

A potential difference of 10v is applied across a conductor of 1000 ohm .the number of electrons flowing through the conductor iin 300s

Answer 1

V=10 V
R=1000 ohm
T=300 s
V=IR          Q=+-ne
10=I*R
10=Q/t*1000
10=n*e/300*1000
10=n*1.6*10 raised to power -19/3*10
30=n*1.6*10 raised to power -18
30/1.6*10 raised to power -18=n
30*10 raised to power -19/1.6
3*10 raised to power 20 / 16 =n
n=3*10 raised to power 20 / 16




 

Answer 2

Answer:1.875×10^-19

Explanation:given,

Potential difference=10V

Resistance=1000ohm

Time=300s

Q=It

But Q=ne and I=V/R

ne=V/R ×t

ne=10/1000×300

n=3/1.6×10^-19

n=1.875×10^19

Hope it helps!
