In the parallel circuit;
Total resistance,
1/R=1/R1+1/R2.
As the number of parallel branches is increased, the total resistance of the circuit is decreased. So, the answer is Decreases.

Total Resistance of Parallel circuit always less than the smallest resistance of the same circuit. Whereas in series Total resistance of the circuit always greater than the largest resistance of the same circuit.

In case of parallel circuits the value of resistance goes on decreasing as we connect the resistors in parallel where as in case of series circuit resistance is increased. Since it gets added with the existing resistors.

In parallel connection, Rtotal = (R1R2)/(R1 +R2).
