By Sukrati Saxena|Updated : July 28th, 2022

As per Ohm’s law V = iR. In this formula, V is the potential difference and i is current and R is resistance. According to this law, R= Vi. when this formular to used to find the dimensional formula of R. V is equal to the work done per unit charge. In this formula when a conductor with a resistance existence and R is connected across a cell of emf V. A potential difference will be created by the cell across the conductor and due to the potential difference, a current will be created in the circuit. 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].

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.

Summary:

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].
