Question

Dimension of resistance in an elecatrical circuit, in terms of dimension of mass `M`, of length `L`, of time `T`, and of current `I`, would be
A. `ML^(2)T^(-3)I^(-2)`
B. `ML^(2)T^(-3)I^(-2)`
C. `ML^(2)T^(-2)`
D. `ML^(2)T^(-1)I^(-1)`

Answer 1

Correct Answer - A
`R=(V)/(I)=(J)/(IC)-=(ML^(2)T^(-2))/(I^(2)T)= ML^(2)T^(-3)I^(-2)`
