CBSE Class 10 Answered

is power directly proportional to the resistence or inversely proportional to resistence?

answered-by-expert Expert Answer

power is inversly proportional to resistance as power is the rate of flow of electrical energy through a conductor with potential diff                      n more energy is used for more resistance.

in P=I2R    =(v/R)2R   =(V2/R2)R

so  P is directly proportional to one power of R bt inversly proportional to two power of R

so on net P is inv prop to one power of R
