Question

In a certain circuit the number of electrons passing a given point in 3 seconds is 6 x 1014 electrons. What is the current flow in this circuit? (Show all work, including substitution with units)

Answer 1

Current = 0.000032 Amperes

Step-by-step explanation:

Given the following data;

Time, t = 3 seconds

Number of electrons = 6 * 10^14 electrons

Conversion:

First of all, we would convert the number of electrons to charge.

Coulombs = electron charge ÷ 6.2415 * 10^18

Coulombs = (6 * 10^14) ÷ (6.2415 * 10^18)

Coulombs = 0.000096 Coulombs

To find the current;

Mathematically, quantity of charge is given by the formula;

Quantity of charge, Q = current * time

Substituting into the formula, we have;

0.000096 = current * 3

`Current = \frac {0.000096}{3}`

Current = 0.000032 Amperes
