Question

define electric current with SI unit and mathematical formula​

Answer 1

Answer:

Electric current is a measure of the amount of electrical charge transferred per unit time. It represents the flow of electrons through a conductive material. THE SI UNIT OF ELECTRIC CURRENT IS THE AMPERE. AND FORMULA IS 1.V: voltage. 2.I: current

Answer 2

$\huge {\underline{\blue{Answer:-}}}$

• The flow of charge at per unit time is called electric current.

• The charge passing per unit time through a given place is the magnitude of electric current at that place.

• SI unit of current is Ampere (A).

• If one coulomb of charge passing through a place in one second, then the current is said to be one ampere.

✧ Mathematical term

• I = Q/t

here,

I is the current

Q is the charge

t is the time.

You can also use Ohm's Law to Calculate the Electric current.

• V = IR

where ,

V is the Potential Difference/Voltage.

I is the Electric Current.

R is the Resistance .
