In a series circuit, adding a resistor will always increase the total series resistance. Removing a resistor (and replacing it with a length of wire, nominally zero resistance) will always decrease the total series resistance.
In a parallel circuit, adding a resistor will always decrease the total parallel resistance. Removing a resistor (and not replacing it with anything, an open circuit) will always increase the total parallel resistance.

Obviously, the overall resistance of the circuit changes (which changes the ammount of current drawn from the power source, and thus the power consumed).
You would have to be more specific.

one million. A. The voltage on the output terminals of the flexibility furnish will enhance because of the decreased voltage drop around the indoors impedance of the flexibility furnish. B. the full modern drawn will cut back because of the upward thrust in entire resistance. C. the full resistance of the circuit will enhance via the ohmic quantity of the resistance extra in sequence to the triumphing circuit. 2. A. The voltage on the output terminals of the flexibility furnish will cut back because of the greater advantageous voltage drop around the indoors impedance of the flexibility furnish. B. the full modern drawn will enhance because of the cut back in entire resistance. C. the full resistance will cut back.
