are u going to answer the questions?

if yes, then here--

what are the Kirchoff's laws of nodes and loops and why is the Kirchoff's sign convention  necessary to use these laws?

i think there's no specific sign convention in kirchoff's laws

if you get the answer in negative,u just took the opposite direction of current 

 

dude my sir told the same thing wow

thanks!

although i haven't studied quantum mechanics much yet so i won't be understanding it

If you want a classical (non-quantum) analogy that will give you the general idea:

Picture two boats floating side-by-side on a lake, with some open water in-between them. The outer sides of the boats are exposed to every sort of wave on the lake... big waves, small waves, long waves and short waves. The inner sides of the boats (facing each other) are exposed to nearly as many types of waves... but not quite. Waves that are too long to fit into the gap between the boats cannot approach them from the inner sides, but can still strike the outer sides.

So even when floating freely on the lake, the boats are subject to unbalanced forces. There are slightly more waves striking the outer sides of the boats than are striking the inner sides. As a result, the boats are slowly and gently pushed closer together. As the distance between them narrows, more and more types of waves are excluded from the zone between the two boats (because as the distance narrows, more and more waves are too long to fit into the narrowing gap) and the force pushing the boats together grows stronger and stronger.

The same principle applies in the quantum world. All of space, everywhere, is seething with pairs of virtual particles being created and destroyed, and each of these particle pairs behaves in some respects as a wave as well as a particle. If you polish two conductive (eg- metal) plates optically smooth and set them very close to each other, the virtual particle pairs between the two plates are suppressed (because their wavelength is too long to fit into the gap) and a net force begins to push the two plates together. The closer together they get, the more particle pairs are excluded and the stronger the force becomes. At assymptotically small distances, it becomes overwhelming.

Ya it's chemistry! And wth is that?

do u have cancer?

Ridhi27004

Are u diagnosed with sage 4 cancer?

Red_Devil007

yes and its too much to ask this in QNA , i not like it
