The correct Answer is:
To solve the problem, we need to calculate the current flowing through a cross-sectional area when a certain number of electrons are passing through it per second. Here are the steps to find the solution: ### Step 1: Identify the number of electrons and the charge of one electron We are given that \( n = 10^6 \) electrons are flowing per second. The charge of a single electron is approximately \( e = 1.6 \times 10^{-19} \) Coulombs. ### Step 2: Calculate the total charge flowing per second The total charge \( Q \) flowing per second can be calculated using the formula: \[ Q = n \cdot e \] Substituting the values: \[ Q = 10^6 \cdot (1.6 \times 10^{-19}) \] Calculating this gives: \[ Q = 1.6 \times 10^{-13} \text{ Coulombs} \] ### Step 3: Calculate the current Current \( I \) is defined as the amount of charge flowing per unit time. Since we are considering the charge flowing in one second, we can express current as: \[ I = \frac{Q}{t} \] Where \( t = 1 \) second. Therefore: \[ I = \frac{1.6 \times 10^{-13}}{1} = 1.6 \times 10^{-13} \text{ Amperes} \] ### Final Answer The current flowing through the area of cross-section is: \[ I = 1.6 \times 10^{-13} \text{ Amperes} \] ---
