Question from student questions physics. The dimensional formula of resistance is given by m 1 l 2 t 3 i 2. It is definitely a characteristic property of each material. Dimensional formula for r ml2t 3a 1 a ml2t 3a 2.

The flow of electric current creates a magnetic field around the conductor. 1 since voltage v electric field distance force charge 1 distance. From faraday s law of induction any change in magnetic field through. Electric resistance potential difference current pd work done charge work done charge current work done ml 2t 2 charge at current a ml 2t 2 at a.

Furthermore experts can use resistivity for comparing different materials on the basis of their ability to conduct electric currents. If ε 0 is the permittivity of free space and e is the electric field then the dimensions of 2 1 ε 0 e 2 is view answer the position of x of a particle at time t is given by x a v 0 1 e a t where v 0 is a constant and a 0.
