Question

which uses more energy , a 250W TV set in 1 hour , krna 1200W toaster in 10 minutes ?​

Answer 1

Answer:

Mark as a brilliant please

Explanation:

The energy consumed by electrical appliances is given by the equation

H = Pt, where P is the power of the appliance and t is the time

Using this formula, the energy consumed by a TV of power ration 250 W, can be calculated as follows:

H = 250 W × 3600 seconds = 9 × 105 J

Similarly, the energy consumed by a toaster of power rating 1200 W is

H = 1200 W × 600 s = 7.2 × 105 J

From the calculations, it can be said that the energy consumed by the TV is greater than the toaster.

Answer 2

Answer:

hope it help

Explanation:

E=Pt

For TV,

E

=250×1=250 Whr

For toaster,
