Question

Через микроамперметр проходит ток 0.8мкА. Сколько электронов проходит через измерительный прибор ежеминутно

Answer 1

I = 0,8 мкА
t = 1 мин = 60 с
q(-e) = 1,6*10^-19
q = I * t = 0,8 * 60 = 48 мкКл

N = q / q(-e) = 48*10^-6 / 1,6*10^-19 = 30*10^13

Answer 2

Calculating the Number of Electrons Passing Through the Ammeter

To calculate the number of electrons passing through the ammeter per minute, we can use the formula:

Number of electrons = (Current in Amperes) * (Time in seconds) / (Charge of one electron)

Given: - Current (I) = 0.8 μA (microamperes) - Time = 1 minute = 60 seconds - Charge of one electron = 1.6 x 10^-19 coulombs

Using the formula, we can calculate the number of electrons passing through the ammeter per minute.

Calculation

Number of electrons = (0.8 x 10^-6 A) * (60 s) / (1.6 x 10^-19 C)

Number of electrons = (0.8 x 10^-6) * (60) / (1.6 x 10^-19)

Number of electrons ≈ 3 x 10^13 electrons

So, approximately 3 x 10^13 electrons pass through the microammeter every minute.
