Dimension formula of electric current
Answers
answer : Ampere
explanation : electric current is one among all seven fundamental quantities. and it has own unit. i.e., Ampere.
so, dimensional formula of electric current is [A].
Although, electric current is derived with help of charge and time. still it has fundamental unit because electric current can be measured easier than charge of any substance.
as we know, electric current is the rate of change of charges flow through wire with respect to time.
i.e., current = charge/time
so, one ampere = one coulomb/one second. [ unit of charge = coulomb and unit of time = second ].
Ampere is the unit of Electric current.
Electric current is defined as the rate of change of flow of charge in a particular time.
The dimensional formula of electric current is often denoted as [A].
We also know that,
unit of charge = coulomb
unit of time = second
Therefore, one ampere = one coulomb/one second
Hope it helps!
