The dimensions of 'resistance' are same ...

The dimensions of 'resistance' are same as those of . . . . . . . . . Where h is the Planck's constant e is the charge .

A

`(h)/(e^(2))`

B

`(h)/(e)`

C

`(h^(2))/(e^(2))`

D

`(h^(2))/(e)`

Text Solution

Verified by Experts

The correct Answer is:
A
`R=(V)/(I)=(W)/(q.I)=(ML^(2)T^(-2))/(A^(2)T)=ML^(2)T^(-3)A^(-2)`
Dim. Of `(h)/(e^(2))=(ML^(2)T^(-1))/(A^(2)T^(2))=[ML^(2)T^(-3)A^(-2)]`
So correct choice is `(a).
