What is the SI unit of electric current Class 7?
The SI unit of electric current is Ampere (A). The SI unit of electric charge is Coulomb.
Why is current an SI unit?
The ampere was then defined as one coulomb of charge per second. In SI, the unit of charge, the coulomb, is defined as the charge carried by one ampere during one second.

Who found the SI unit of electric current?
Class 10 Question. Current intensity is often referred to simply as current. The I symbol was used by André-Marie Ampère, after whom the unit of electric current is named, in formulating Ampère’s force law (1820). The SI unit of electric current is Ampere (A) and was discovered by scientist Andre Marie Ampere in 1820.. …
What is the SI unit of electric current and electric charge?
Explanation: The coulomb, C , is derived from the fundamental SI unit of time, the second, s , and the fundamental SI unit of electric current, the ampere, A . It is the charge (Q or q) transported by a constant current of one ampere in one second.
