Question

1 billion electron pass from a point A to B in a conductor in 10^_4 sec what is the magnitude and direction of current

Answer 1

if 1 billion electrons are flowing then the total charge will be 10^9 x 1.6 x 10^-19 c
= 1.6 x 10^-10 coloumb
acc. to formula Q= iT
WHERE i is the current and t is time
1.6 x 10^-10 = i x 10^4
i = 1.6 x 10^-14 ampere
the magnitude of current will be 1.6 x 10^-19 AMPERE
and the direction of flow of current will be opposite to the direction of flow of electrons

Answer 2

Answer:

if 1 billion electrons are flowing then the total charge will be 10^9 x 1.6 x 10^-19 c

= 1.6 x 10^-10 coloumb

acc. to formula Q= iT

WHERE i is the current and t is time

1.6 x 10^-10 = i x 10^4

i = 1.6 x 10^-14 ampere

the magnitude of current will be 1.6 x 10^-19 AMPERE

and the direction of flow of current will be opposite to the direction of flow of electrons
