Expert Answer
Let i1 , i2 , i3 and i4 be the current passing through the junction as shown in figure.
hence as per the figure, i1 + i3 = i2 + i4 ........................(1)
let the potential at J be X.
Hence currents in eqn.(1) can be written in terms of potential differences and the respective resistances.
(40-X)/4 + (30-X)/3 = (X-10)/1 + (X-20)/2 ................(2)
Solving the eqn.(2) for X, we get X ≈ 19.2 V
