In the given network, the potential at point `O` is (Given `VO = V_(s) = 18 V)`

A

`9 V`

B

`780//47 V`

C

`680//43 V`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
(b) `I = (V_(0) - V_(s))/(1) = 18 A`
`I_(1) + I_(2) + I_(3) = I`
`(33 - V_(0))/(3) + (40 - V_(0))/(4) + (50 + V_(0))/(5) = 18`
`implies V_(0) = 780//47 V`
