So I was curious about parallel circuit. I first built four branches and only filled them with three light bulbs. Surprisingly, it looks something weird like the picture below (first one). When I filled the fourth branch with a light bulb, everything light equally and even brighter.

Okay, here's what I know. I know that the wire that is outside the branch (and connects with the fourth branch) has more current for sure because there is no resistance. However, why the first light bulb got brighter than the second one and so on? Secondly, why is the circuit with 4 light bulbs is brighter?

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -

Depending on how the continental plates move it can cause a continental scale shift.

Well the magnitude of its acceleration related to that car starts with the oil change like when you have to change the oil in your car you have to make sure that your precious car is starting really propley and very well

One splits the atoms and molecules  the other combines them
