Dimensions of resistance in an electrical circuit, in terms of dimension of mass M, of length L, of time T and of current I would be
Options
(a) [ML²T⁻²]
(b) [ML²T⁻¹I⁻¹]
(c) [ML²T⁻³I⁻²]
(d) [ML²T⁻³I⁻¹]
Correct Answer:
[ML²T⁻³I⁻²]
Explanation:
According to Ohm’s law,
V=RI or R = V/I
Dimensions of V=W/q = [ML²T⁻²]/[IT]
R=[ML²T⁻²/IT]/[I] =[ML²T⁻³I⁻²]
