   What is current and the unit to measure it?

   • Let us know what is current and the unit to measure it. The magnitude of electric current is measured in coulombs per second. The SI unit of electric current is Ampere and is denoted by the letter A. Ampere is defined as one coulomb of charge moving past a point in one second.

   What is electric current?

   • Electric current is defined to be the rate at which charge flows. A large current, such as that used to start a truck engine, moves a large amount of charge in a small time, whereas a small current, such as that used to operate a hand-held calculator, moves a small amount of charge over a long period of time.

   How does electrical current work?

   • The electrical current in the basic term is the flow of electric charge. The common electric charge carriers are electrons, but they can also be ions as in the case of chemical batteries. To understand how electrical current works let us look at the flow of water as an analogy. Consider a tall container fitted with a tap at the bottom.
