Question

write down the energy consumption of the given devices (a) television (b) refrigerator (c) air conditioner (d) microwave​

Answer 1

Explanation:

a) How much electricity does my television use? Most TV's use about 80 to 400 watts, depending on the size and technology. Using a sample cost of 15¢ per kilowatt-hour and five hours of viewing a day, that's $1.83 to $9.13/mo.

b) Domestic fridge power consumption is typically between 100 and 250 watts. Over a full day, a fridge is likely to use between 1 to 2 kilowatt-hours (kWh). This translates into a running cost of about $150 per year per fridge.

c) cooling capacity of 1 ton is equal to 3.517 kW of power. For 1.5 ton AC ,power consumption of ac =cooling capacity/EER. =1.5*3.517/2.7=1.954 kW. AC consists of two units, Indoor unit which is called the evaporator and the Outdoor Unit which called the Compressor.

d) Compact microwaves use between 500 and 800 watts during heating, while a regular sized microwave will use 850 to 1800 watts depending on the model. An average modern microwave will use around 1200 watts.
