Combine three resistors `5Omega, 4.5Omega and 3Omega` in such a way that the total resistance of this combination is maximum

A

`12.5Omega`

B

`13.5Omega`

C

`14.5Omega`

D

`16.5Omega`

Text Solution

Verified by Experts

The correct Answer is:
A
For maximum equivalent or total resistance of the resistors must be combined in series.
`R_(eq)=R_(1)+R_(2)=R_(3)=5+4.5+3=12.5Omega`
