Question

Q.1 A current of 10 A flows through a conductor for two minutes . [ I ] Calculate the amount of charge passed through any area of cross section of conductor . [ II ] If the charge of an electron is 1.6 x 10^ -19 C , then calculate the total number of , electrons flowing .

Answer 1

explanation⬇

here $I_{current}$=10A,

$t_{time}$=2min (or) 300sec

part one➡

from relation,

I=$\frac{q}{t}$

q=I*t

q=10Asec-¹*300sec

q=3000coulomb.

part two➡

from relation,

q=ne

n=$\frac{q}{e}$

n=$\frac{3000}{1.6\times{10}^{-19}}$

n=$\frac{3000\times{10}^{19}}{1.6}$

n=1875*${10}^{19}$

n=1.9*10²² electron.
