A resistor \[{{R}_{1}}\] dissipates the power P when connected to a certain generator. If the resistor \[{{R}_{2}}\] is put in series with \[{{R}_{1}}\], the power dissipated by \[{{R}_{1}}\] [CPMT 1985; MNR 1998]

• A.            Decreases
• B.            Increases
• C.            Remains the same             
• D.            Any of the above depending upon the relative values of \[{{R}_{1}}\] and \[{{R}_{2}}\]
