Answer:

Hey mate

current (i) = (number (n)× charge on electron (e))÷time

therefore i = ne ÷ t

by putting the value

1 = n × 1.6×10^-19 ÷1

n = 1 ÷ 1.6× 10^-19

n = 0.625×10^19

» n = 6.25 × 10^18

¡.e

» n = 6 × 10^18

hence,number of electrons that flow through any section of conductor in 1 second with 1 A current is 6 × 10^18

The number of electrons?

Current (Q) = 1 ampere.

Time(t) =1 second.

\huge\underline\mathtt\red{FormulaUsed}

I =  \frac{Q}{t}

Here,

I = Strength of current

Q=Amount of charges flowing

t=Time in second unit

\huge\underline\mathtt\red{Calculation}

I = ne \div 1

Now,by putting the values,we get,

\sf{1 = n \times 1.6 \times  {10}^{ - 19}  \div 1}

\sf{n = 1 \div 1.6 \times  {10}^{ - 19} }

\sf{n = 0.65 \times  {10}^{ - 19} }

\rule{300}{2}

The amount of positive charge that flows through any cross-section of a conductor in every second is called the strength of current in that conductor.

Strength of current is a scalar quantity, although it has direction.

Dimension of current strength =[ I ].

Unit of strength of current:

CGS unit of current strength is emu(Electromagnetic unit) and its SI unit is Ampere (A).

If through any cross-section of a conductor 1 columb of charge flows for 1 second, then the strength of current through that conductor is said to be 1 ampere (A).

\underline{\boxed{\mathtt{\green{1 \: emu \: of \: current \: strength \:  = 10A}}}}
