Question

define 1A electric current
​

Answer 1

Answer:

1 coulomb / 1 second

Explanation:

the  conventional direction of an electric current is the direction in which a positive charge would move. Henceforth, the current flowing in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery.

Answer 2

Answer :

▶ One ampere is that amount of current when an electric charge of one coulomb flows through a cross section of wire in one second .

i.e. ${\sf{\red{1A\:=\: \dfrac{1C}{1s}}}}$

▶ S.I. unit of current is ampere .

▶ Device used to measure current is ammeter .
