What is : (a) the highest (b) the lowest total resistances that can be obtained by combinations of four coils of resistances `4 Omega,8 Omega,12 Omega,24 Omega` ?

Text Solution

Verified by Experts

The lowest total resistance is given by
`(1)/(R )=(1)/(R_(1))+(1)/(R_(2))+(1)/(R_(3))+(1)/(R_(4))`
`R=24/12 =2omega`
