The series combination of two 10 ohm resistances is connected in parallel combination with a 20 ohm resistance. Determine the equivalent resistance of the final combination.

Show that if a resistance connected in a parallel combination is much smaller than the other resistance of the combination,then the equivalent resistance of the combination is almost equal to the small resistance.

R_1 and R_2 are two resistances they are connected in parallel combinations Write down their equivalent resistance in each case.

In parallel combination of resistance-
