Question

5. Calculate the number of electrons that would flow per second through the cross- section of a wire when 1 A current flows in it.

Answer 1

Answer:

6.25X10^18

Explanation:

When one coulomb charge passes through any cross section of the wire per second,the current passing is one ampere.

Charge of electron ,e=1.6X10^-19C.

Suppose, there are n electrons in 1C charge, then,

ne=1C

n=1/(1.6X10^-19)=6.25X10^18. This number of electrons passes through cross section of a wire carrying 1A current.

Answer 2

Answer:

6.25×10^18

Explanation:

The number of electrons is this!
