2, 4 and 6 S are the conductance of three conductors. When they are joined in parallel, their equivalent conductance will be

A

12 S

B

`(1//12)S`

C

`(12//11)S`

D

`(11//12)S`

Text Solution

Verified by Experts

The correct Answer is:
A
`R_(1)=1//2Omega,R_(2)=1//4Omega, R_3 =1//6Omega`
In parallel :
`1/R_p=1/R_1+1/R_2+1/R_3 =2 + 4 + 6 = 12`
or Equivalent conductance,
`G= 1/R_p= 12S`
