Which uses more energy 250W TV set in 1 hour or 1200W toaster in 10minutes |
|
Answer» For T.V SET Power (P) = 250w, Time (t) = 1hr=60×60=3600s For TOASTER Power (P) = 1200w, Time (t) = 10min=10×60=600s We know that Energy (E) = P×t ∴ Energy consumed by a TV set = 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 energy consumed by a toaster of power 1200 W in 10 minutes. |
