The equivalent resistance between points...

The equivalent resistance between points A and B in the following electric circuit is ……………… .

A

`2.5 Omega`

B

`5 Omega`

C

`12.5 Omega`

D

`20 Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
Resistors `R_1 and R_2` are connected in parallel.
`:. R. = (R_1 R_2)/(R_1 + R_2) = (5 xx 5)/(5 + 5) = 2.5 Omega`
Now, `R., R_3 and R_5` are connected in series
`:. R = R. + R_3 + R_5`
`=2.5 + 5 + 5 = 12.5 Omega`
