Question

(4)
If M= mass. L = length, T = time and I = electric
current then the dimensional formula for electrical
resistance R is given by
(1) [M'L-TI-?) (2) (M'L’T-131
(3) [M'L-TI-?) (4) [M'L-TI)​

Answer 1

Answer:

i^2 *R*T = heat= energy

therefore R= energy/(i^2*T).

put the dimensions for energy in terms of mass, length and time and solve the question.
