Question

What is the dimentional formula of energy and electric current​

Answer 1

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

Answer 2

Answer: energy: 1M,1L, -2T
