To find the total resistance of all components, the reciprocals of the resistances of each component are added and the reciprocal of the sum is taken.
Thus, the Total resistance will always be less than the value of the smallest resistance.

Ans is decrease for example there are 2 resistor of 3ohm n 4ohm total Resistance in series will be 3+4=7ohm and total resistance in parallel will be {1/3+1/4}^-1=12/7=1.7ohm approx so total resistance is decrease when the connection is in parallel...

Decreases !!!. Because, Suppose we take in series combination by using formula Rs = R1 + R2 + R3, where R1 = 3, R2 = 2, R3 = 1.
3 + 2 + 1 = 6Ω!!!.
Let we take in a parallel by using formula 1/Rp = 1/R1 + 1/R2 + 1/R3, where R1 = 3, R2 = 2, R3 =1.
1/3 + 1/2 + 1/1
= 1/3 × 6 + 1/2×6 + 1/1 × 6/6
= 2 + 3 + 6/6
= 11/6
= 1.83 Ω.
Compare the resistance in series and also in parallel. Now, you can clearly know that in parallel combination, total resistance decreases.
3 + 2 + 1 = 6Ω!!!.
