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)

Current = 0.000032 Amperes

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 = 0.000032 Amperes

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.

the answer is 100. i just did this lesson and got a 100% on it. : )
