Question

define electric current. write its formula and define it unit. ​

Answer 1

Answer:

electric current is the amount of charge passing through a particular area of cross section in unit time.

its formula is I=Q/T

its unit is ampere

1 ampere is constituted by the flow of one coulomb per second.

Answer 2

Answer:

electric current, I = q/t, it is the amount of charge flowing per unit time.It is a scalar quantity, even though it has direction, because it does not obey vector algebra. Its direction is opposite to the flow of electrons.

Ampere Is the unit of current

Ampere is that amount of current produced when two long straight conductors kept 1 cm apart in vacuum produces between them a force of 2 *10^-7 N/M.
