Define electric current and write its equation

Here is your answer

Electric current is defined as the rate of flow of charge through a conductor in cross section area.

Its equation

I= q/t

where,

I= electric current

q= charge

t= time

SI unit of current is Ampere (A)

HOPE IT IS USEFUL

Electrical current-the movement of charge past a certain point per unit of time.

I=Q/t

Explanation:

like poles repel so keep pushing north to north and repels funny to see this

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
