In a circuit four resistors of `1 Omega ,2 Omega, 6 Omega and 12 Omega` respectively are connected in series combination. The maximum resistance that can be obtained is

`21 Omega`

`18 Omega`

`6 Omega`

`4 Omega`

Text Solution

Verified by Experts

In series resistance the resistance of the combination is
`R=R_1+R_2+R_3+R_4=(1+2+6+12) Omega=21 Omega`
