Unit of Current

 

Introduction:

We have heard a lot about electric currents in our classrooms and at home. While the topic is highly relatable, in more scientific terms an electric current is basically a flow of current or charge in electric circuits.

Sometimes both ions and electrons carry the charge simultaneously. Electric current or charge is measured by an ammeter, and there are different measurement methods as well as units of current. Here we will look at some of them in detail.

  Ampere is one of the SI base units for electric current. It is used in electronic and electrical science as well as other areas of science. The definition of ampere is based on the electromagnetic effect it induces.
