Serires and parallel combination

1/In series combination the total resistance is sum of individual resistances, hence the equivalent resistance is greater, while in parallel combination the equivalent resistance is less than the individual resistance.

2/In series resistances the electric current is the same through all of them, while is parallel it's distributed through the resistances unevenly if the resistances are different.

3/The potential difference is same across all resistor in parallel combination while it's not for series combination.
