the key point in these paragraphs is to conveys the reason why and how current flows in any conducter... its due to free electrons in solid conductors and in liquid electrolytes its bco of ions. as they also carry charge .. and movemmet of charge is called current . . in a specific area of cross section the number of electrons passed (n) and charge on each electron (1.6 ×10^-19 C ) is when multiplied we get the total number of charges passed which when divided by time gives current ...
which the formula is based on..
