Question

Why charge is not an fundamental quantity but electric current is?

Answer 1

Concept introduction:

When putting in an electric and magnetic field, a minuscule particle's electric charge leads it to perceive force. Positive and negative charges are the two forms of electricity.

Explanation:

We have to answer this question.

A question regarding electric charge and current has been given to us.

For a quantity to be fundamental we should be able to measure it directly. E.g you can measure mass and length directly, so they are fundamental. However we have no instrument to measure the magnitude of charge, we have instruments to find whether a body is positively or negatively charged or which is more charged and which ones less but we don't have any instrument to measure the magnitude. Since we can measure current directly with ammeter so it is the fundamental quantity though it comes due to flow of charge per unit time.

Final answer:

Here we have written the why the electric charge is not an fundamental quantity but electric current is and this is our final answer also.
