For T.V set                                                                                                                             Power (P) = 250w,                                                                                                              Time (t) = 1hr=60×60=3600s                   
for toster
power=1200W
time =10min = 10*60 =600s
E=P*T
Energy consumed by the TVset = 250*3600 =9*105J                                                            ∴ Energy consumed by a toaster = 1200 × 600 = 7.2× 105J                                               ∴ the energy consumed by a 250 W TV set in 1 h is more than the energyconsumed by a toaster of power 1200 W in 10 minutes.
