1. A charge of 1,67 C flows through the filament of a particular light bulb in 2,00 s. 1a) Calculate the current flowing through the light bulb. (b) Calculate the number of electrons that pass through the filament every second. 2. A current of 5 A flows through a wire for 4,0 minutes. How much charge passes through any given cross-section of the wire?​

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 -
