Question

В однородном проводнике скорость направленного движения электронов равна 0,5 м/с . Определить велечину силы тока через проводник при условии, что в 1 м длинны проводника сумма зарядов движущихся электронов равна по абсалютной величене 3 Кл.

Answer 1

I=n*V*S*e(1)
n=N/S*L   N=q/e  n=q/S*L*e(2) Подставим 2 в 1
 I=q*V/L=3*0,5/1=1,5 A  

Answer 2

Calculating the Current in the Conductor

To calculate the current in the conductor, we can use the formula:

I = n * A * e * v

Where: - I = current - n = number of charge carriers per unit volume - A = cross-sectional area of the conductor - e = elementary charge - v = drift velocity of the charge carriers

Given: - Drift velocity (v) = 0.5 m/s - Length of the conductor (l) = 1 m - Total charge of the moving electrons (Q) = 3 C

We can calculate the number of charge carriers per unit volume (n) using the formula:

n = Q / (e * l)

Let's calculate n using the given values.

Calculating the Number of Charge Carriers per Unit Volume

n = Q / (e * l) n = 3 / (1.6 * 1) n = 1.875 * 10^18 m^-3

Calculating the Current

Now, we can calculate the current (I) using the formula:

I = n * A * e * v

We are given the drift velocity (v) but not the cross-sectional area (A). Without the value of the cross-sectional area, it is not possible to calculate the current using the given information.

If you have the value of the cross-sectional area, please provide it, and I can help you calculate the current through the conductor.
