Question

Find The Potential Of The Junction O?​

Answer 1

Answer:

200V

Explanation:

Using Q=C∆V

Suppose at point O potential is V..

then we can use junction law at point O i.e. sum of all the charge flowing from O will be zero

hence...

3(V-100) + 1(V - 300) + 2(V - 400) = 0

by solving...

we get V = 200Volt

this is our required answer.
