How many electrons should flow per seconds to constitute a current of magnitude one ampere ?

Explanation

To determine how many electrons should flow per second to constitute a current of magnitude one ampere, we can follow these steps:

### Step 1: Understand the relationship between current, charge, and time
The current (I) is defined as the amount of charge (Q) that flows through a conductor per unit time (t). Mathematically, this is expressed as:
\[ I = \frac{Q}{t} \]

### Step 2: Express charge in terms of the number of electrons
The total charge (Q) can also be expressed in terms of the number of electrons (n) and the charge of a single electron (e). The relationship is given by:
