Question

3. Why does it take large number of electrons make up a single useful amount of charge?

A) Electrons are useless on their own

B) The amount of charge on a single electron is almost insignificant

C) Electricity requires a lot of electrons

D) Electrons are easily destroyed​

Answer 1

Answer:
The answer is B

Step-by-step explanation:

Electrons have a negative charge and are fundamental particles that make up atoms. However, the charge on a single electron is very small, approximately -1.6 x 10^-19 coulombs. As a result, it takes a very large number of electrons to make up a single useful amount of charge. For example, a typical AA battery contains approximately 6 x 10^21 electrons. This is because electricity is typically measured in terms of coulombs, which is a unit of charge. Therefore, the larger the number of electrons, the greater the amount of charge, and the more useful the electricity is for various applications.
