Difference Between Charge and Current

As we know, charge and current are the two most common key terms in the field of electrical and electronics and communication engineering. Most of the times these terms confuse the newbie or those who just started learning the electronics sciences. 

The key difference between the charge and the current is that the charge is the physical property of matter while the current is the rate of flow of charges. Here this article gives the information about the difference between charge and current are listed below


Definition of charge:

The charge is a fundamental property of particles that allow them to interact with each other via electromagnetic forces. During these interactions, the charge is always conserved. Electric charges could be either positive or negative. As we know that a positive charge refers to the charge carried by a proton while negative charge refers to the charge carried by an electron. 

Definition of  current:

Current is measured in the unit of amperes(A). A current of 1 A refers to the flow of charge where 1 C of charges flow past a point every second. 

The main key difference between charge and current are listed below:

  • The charge experiences the force only in the electrical field, wheres the current experience the force both in the electric and magnetic fields.
  • The coulomb is the unit of electric charges while the current in the measured the amperes.
  • The charge is the property of matter because of which the matter experiences the force of attraction or repulsion in an electric field. While the current is the rate of flow of charged particles called electrons.
