A resistor R1 dissipates the power P when connected to a certain generator.If a resistance R2 is put in series with R1 the power dissipated by R1 decreases.Give reasons Share with your friends Share 4 Akansha Tyagi answered this Power dissipation,P=V2R1Equivalent Resistance,R=R1+R2Power dissipation,P=V2R (1)It is clearly shown that the equivalent resistance gets increases so the Power disipation will decrease. 12 View Full Answer
