Show that the equivalent resistance of a parallel combination is less than every individual resistance of that combination.

Show that the equivalent resistance of a series combination is greater than every individual resistance of that combination.

The equivalent resistance of the parallel combination is:

The equivalent resistance in series combination is :

Show that equivalent resistance in parallel combination is always less than each of the individual resistances connected in the combination.

Show that equivalent resistance in parallel combination is always less than each of the individual resistances connected in the combination.
