Answer: The dimensions of electrical resistance is =[M1L2T−3A−2]
The electrical resistance of a given substance can be defined as the ability of the substance to resist the flow of electrons or charges. When a potential difference is created across the substance resistance may occur. In such cases, the flow of charges per unit of time can be defined as current in the circuit.
The dimensions of electrical resistance are:
The dimensions of electrical resistance is =[M1L2T−3A−2]. As per Ohm’s law V = iR. In this formula, if resistance is R and the current in the circuit is i, then, Ohm’s law will be applied, V = iR. Hence [R]=[ML2T−3A−1] and [A]=[ML2T−3A−2].
