For both a series and parallel circuit if i am using the same battery with a switch the resistance should be the same for both of them. Right?

But i am using Ohm's law

the resistance in a series cicuit is just the sum of all the resistors but in a parallel circuit
1 / Total resistance = 1 / resistor 1 + 1 / resistor 2 . . and so on
if your calculations are correct the total resistance in a parallel circuit should be smaller than the resistance of the smallest resister in the circuit.

the equivalent resistance for the circuit will be lower for parallel. Are you looking for the resistance across whatever is hooked up to the switch, that would remain constant although the voltage passing through it would be different. Vout=Vin*(R1/(R1+R2))

Total resistance for:
resistors in parallel = R1 + R2 + R3 + ....
resistors in series = 1/( 1/R1 + 1/R2 + 1/R3 + .... )

You didn't describe the other components in the circuit, but I suspect the answer is "No."
