Question

define the unit of current .

please give your own answer .
​

Answer 1

Answer:

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.

Apart from ampere, there are several standard units of measurement used for the expression of electrical properties like the voltage, resistance, power, capacitance, inductance, electric field, electric charge, frequency, the magnetic flux which are all related to electric current.

I hope it's clear you doubt army!

Answer 2

Answer:

The SI unit of current is amper which measures the flow of electric charge across a surface at the rate of one coulomb per second. Since charge is measured in coulumbs and times in second, so unit is coulumb/sec (c/s) or amp meanwhile the formula for electric current is given as follows :

I=V/R

• I= electric current
• V=voltage
• R=resistance of materials
