realy sorry but i don't know pardon mr for this
soooooooooooorrryyyyyy
The current in the junction is 1350 mA or 1.350 A.
Explanation:
As per Kirchoff's first law, the algebraic sum of current meeting at any junction should be equal to the algebraic sum of current leaving the junction. As in the present case, three parallel branch circuit is given the current in 250 mA, 300 mA and 800 mA, respectively, the sum of these three current will be equal to the current in the junction.
So,
I₁+I₂+I₃ = I₄
So I₁,I₂ and I₃ are the current passed in the three parallel branches and I₄ is the current in the junction.
250 + 300 + 800 = 1350 mA
So the current in the junction is 1350 mA or 1.350 A.

Explanation:
The magnitude of the electric field between the plates is given by
E = -ΔV/d
minus sign indicates Potential decreases in the direction of electric field
where
ΔV is the potential difference between the plates
D is the distance between the plates.
The work done when carrying an electrical charge on an equipotential surface between one position to the other is zero W= q(V-V)=0 The electric field lines of force are always perpendicular to an equipotential surface. That conductor in an equipotential surface as direction E is at right angles to an eauipotential surface The intensity of the electric field along an equipotential surface is always zero. Equipotential surfaces never collide with each other as this would mean that at that point, there are two alternative values that are not true.
