Talking about current and electric charge, cannot be separated from the history of the discovery of electricity itself, where in 1897, J. J. Thomson first discovered electrons at the Cavendish Laboratory, Cambridge University, when he was studying cathode rays.
I can explain the current and electric charge itself as follows:
1. Electric Current
If the electrons are moving, free from the influence of the atomic nucleus, and there is a flow, this flow is known as electric current. Electric charge can be measured directly using an electrometer, while electric current can be measured directly using a galvanometer.
What is known as static electricity is not the flow of electrons at all. More precisely called a static charge, when an object has more or less electrons than needed to compensate for the positive charge. If there is an excess of electrons, it is said to be "negatively charged". But if there is a lack of electrons, it is called "positively charged". And if the number of electrons and protons is the same, it is called neutral.
Electric current is the amount of electric charge that flows per unit of time. Electric charge can flow through cables or other electrical conductive materials. The unit for measuring electric current is called the Ampere (A).
2. Electric Charge
Electric charge, which is denoted by Q, is a measurement of the basic charge possessed by an object. The unit Q is the coulomb, which is 6.24 X 1018 base charge. Q is the basic property possessed by an object, whether it is a proton (positive charge) or an electron (negative charge). The total electric charge of an atom or object can be positive, and can be negative, depending on the amount of charge atoms contained in it. Therefore, the charge of the object or atom is a multiple of the basic Q unit. In a neutral atom, the number of protons will be the same as the number of electrons surrounding it (forming a total neutral or uncharged charge).
Thus a description of the current and electric charge, hopefully this is useful. And also follow the description or other related articles here.
