The unit of electric current is the ampere, symbolized as "A." Electric current is the flow of electric charge through a conductor, typically measured in amperes (amps). One ampere is defined as the flow of one coulomb of charge per second. In other words, if a current of 1 ampere flows through a conductor, it means that 1 coulomb of electric charge passes through that conductor in 1 second.
Mathematically, it can be expressed as:
1 Ampere (A) = 1 Coulomb (C) / 1 second (s)
Electric current is a fundamental concept in electricity and plays a crucial role in various electrical devices and systems.
