Kirchhoff’s First law: Junction law

Junction Law is also known as Kirchhoff’s First Law.
It states that at the junction,sum of current entering the junction is equal to the sum of current leaving the junction.
Junction is any point in the circuit.
Consider a case where I1 and I2are the currententering the junction and,currentI4 and I5 are exiting out of the junction.
According to Kirchhoff’s law; I₁+ I₂ =I₃+ I₄+ I₅

As electric field inside a hollow charged conductor is zero which means that the line integral of $\vec{E}$ is zero. This results in the fact that Electric potential at the surface and at any point inside the conductor is same.

I am not physics expert aur genius but I will give this answer becoz it's the easiest one. look for hydrogen like ions, the radius of the nth orbit is ➡️ an = n²aο/Z. ✴️ for Li++, z=3 and in ground state n=1. the radius is ➡️ a1=53pm/3 which is approx 18pm. # this question doesn't need any expert ?but gud question ??

Statement of Gauss"s Theorem : The net-outward normal electric flux through any closed surface of any shape is equal to

1/ε₀times the total charge contained within that surface , i.e.,

over the whole of the closed surface, q is the algebraic sum of all the charges (i.e., net charge in coulombs) enclosed by surface S.

Proof of Gauss"s Theorem :

Let a point charge +q coulomb be placed at O within the closed surface. Let E be the electric field strength at P. Let

OP= r and the permittivity of free space or vaccuum be ε_0.

Becoz sunglasses outer surface are convex and inner are concave . If the power of glasses are equal made then the power of glasses reduced to zero. Thus, the glasses behaves like a thin sheet of glass instead of lenses.

Akancha Srivastava 6 years, 5 months ago

All the electrons get drifted(means have very slow velocity due to colloiding with other atoms or electron)in the opposite direction of electric field.. jab wo electron acceleration se aata h fir wo collision ke kam ho jaata hai aur use gain hoti hai ek slow velocity called drift velocity

Jk Verma 6 years, 5 months ago

It is the average velocity with which electrons get drifted towards the positive end of the conductor in opposition to applied electric field.
