CBSE Class 10 Answered

Out of 60W and 40W lamps, which one has higher electrical resistance when in use?
Asked by | 10 Jan, 2010, 08:24: PM
answered-by-expert Expert Answer

The 60 W will have higher resistance, since higher power means higher temperature of the filament, higher kinetic energy of electrons, more frequently collision.

Hence higher resistance.
