Question

In, a potential of `+12 V` is given to point A, and point B is earthed. What is the potential at the point P in V?
.

Answer 1

Correct Answer - 4
(4) `DeltaV_(AP)=Q/3, DeltaV_(PB)=Q/6 [:. (4+2) muF=6 muF]`
Also, `Q/3+Q/6=12` or `Q=24 muC`
`DeltaV_(AP)=(24)/3=8` or `V_(A)-V_(P)=8`
or `12- V_(P)=8` or `V_(P)=4V`.
