Question

define current what is its si and cjs unit given their symbol​

Answer 1

Answer:

electric current is basically a flow of current or charge in electric circuits.The SI unit of current is ampere which measures the flow of electric charge across a surface at the rate of one coulomb per second. Since the charge is measured in coulombs and time in seconds, so the unit is coulomb/Sec (C/s) or amp. Meanwhile, the formula for electric current is given as follows:

I = V/R

Where,

I = Electric Current

V = Voltage

R = Resistance of the material

Ampere is one of the SI base units for electric current. It is used in electronic and electrical science as well as other areas of science. The definition of ampere is based on the electromagnetic effect it induces.

Answer 2

Answer:

Explanation:

Electric current is rate of flow of  electric charge or the amount of charge flowing through a particular point in unit time.

I=Q/T

where,

I=Electric current

Q=Electric charge

T=Time

Unit is Ampere(A)
