Define the unit of current ?

⠀ ⠀|| ☆.ANSWER.☆ ||

Definition :-

In simple form :-

" Current is a flow of charge "

Or,

" Electric current in a wire , where the charge carrier of electrons is a measure of quantity passing any point of the wire per unit of time " .

Denote:-

  • Current denoted by capital "I" .

Relation between I, V and R

By, Ohm's low,

  • I = V/R

where,

  • I = current
  • V = Voltage
  • R = Resistance

Units:-

  • Ampere

Symbol :-

  • Denoted by capital " A "

Current measure :-

  • Electric current measured by " ammeter "

Answer:

  • The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second.
  • When the charge of electrons flows through the cross section of the electrical conductor in relevance to measure of unit of time in seconds, the unit coulomb of charge passed in unit seconds is called an Ampere. ... Therefore, the unit of Current is Ampere which is measure of charge passed in unit time.
  • The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second.

In this everything is correct... According to you, which one you feel comfortable, you can go with that....
