Five resistors are connected as shown in...

Five resistors are connected as shown in adjoining figure.

The effective resistance i.e., equivalent resistance between the points A and B is:

A

`4Omega`

B

`5Omega`

C

`15Omega`

D

`20Omega`

Text Solution

Verified by Experts

The correct Answer is:
A
`R_(AB) = (R_(1)R_(2))/(R_(1) +R_(2))`
`R_(AB) = (5 xx 20)/( 5 +20)`
`=(100)/(25)`
`=4Omega`
