Which arrangement of 3Omega resistors wi...

Which arrangement of `3Omega` resistors will give a total resistance of `7Omega`?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
Three resistors of `3Omega` each in parallel will give
`((1)/((1)/(3)+(1)/(3)+(1)/(3)))=1Omega`
`R_("eq")=3+1+3=7Omega`
