# Differences charge quantity and electric charge

First of all,my english is not well,so sorry for reading. As a senior middle school from China mainland,I am teaching physics about electri field.I with my workmates,get a problem now.We can not get a agreement.There are three viewpoints.

The first is that,electric charge is physical attribute and a physical quantity.It means electric charge is a physical quantity.The unit of electrical charge is the coulomb (symbolized C).

The second is that,electric charge is physical attribute.Charge quantity is a physical quantity.The unit of charge quantity is the coulomb (symbolized C). Electric charge has no unit.

The third is that,electric charge is physical attribute and a physical quantity.Charge quantity is a physical quantity too.The unit of electrical charge is the coulomb (symbolized C). The unit of charge quantity is the coulomb (symbolized C) too.

• When you say "charge quantity", do you mean something like "the number of objects with electric charge"? – probably_someone Sep 4 at 14:24

• by a unit of measurement, which is a definite magnitude decided by a convention ($$C$$, $$e$$, $$\frac{[Current Intensity]}{[Time]}$$, ...)
