Question

24. Which uses more energy in the following
1) 250W of Television set in one hour
2) 1200W of toaster in 10 minutes​

Answer 1

Answer:

250 w of television in one hour...

Answer 2

Answer:

I) Television

power= 250W= 250/1000= 0.25kw

time= 1 hour

energy= power× time

0.25× 1

0.25kwh

2) Toaster

power= 1200w= 1200/1000= 1.2 kw

time= 10 mins= 10/60= 0.16 hours

energy= power× time

1.2× 0.16

0.192kwh

Therefore, toaster uses more energy than the television.
