How many watts does a microwave use?

Answer 1

700 watts is s not a good microwave for bag Popcorn ( I have cooked many half burnt-half cooked bags) but about everything else it took a little longer but it was fine. 900 watts will cook about everything fine but will take a little longer than a 1000 watt or higher microwave

Answer 2

Answer #1:

800 watt is the wattage in that case. That refers to how much power

a device uses.

========================

Answer #2:

When you see an ad for an "800-watt microwave oven", that number is

invariably the "cooking power" ... the 2.5 GHz RF power that's generated

by the magnetron and radiated into the chamber to heat the meatloaf.

Your question suggests that you understand that the appliance uses more

power than that from the outlet while it's cooking.

The relationship between cooking power and total operating power is not

necessarily the same for all brands, sizes, and styles. We're really talking

about efficiency here ... the fraction of the input power that's ultimately

presented to the meatloaf ... and that can certainly vary according to the

design of the machine.

The microwave oven that hangs from the bottom of the cabinet over my

stove is advertised as "1200 watts" of cooking power, and the little plate

on the back says that it needs 1.58 KW of electric power to operate.

That means that it's nominally 76% efficient, and it uses 1.32 as much power

as it delivers to the cooking chamber.

There's no way to know whether your 800-watt unit is similar. IF it is, then

it would need about 1,050 watts from the wall while it's running ... about

8.8 amps on a nominal 120VAC circuit.

That's not a horrendous intermittent load for a modern kitchen appliance.

Still, if your house was wired some years ago, AND you have some lights

on AND the refrigerator is running AND you're making toast at the same

time that the microwave is cooking, the combination could trip a breaker

or blow a fuse.

Answer 3

"Watt per minute" doesn't make sense. Watt is a unit of power, and means "joules per second". So, an electrical device will use a certain amount of power (watts) while it is on - no matter how long you leave it on. Typical microwaves probably use around 1000 watts.

Answer 4

A typical microwave oven uses around 700-1200 watts during cooking. It may use less power during standby mode or when the door is open.

Answer 5

That depends on the make and model of the microwave. Look in the door jam, there should be a label that states its power consumption.

Answer 6

Find the nameplate rating it will say volts amperes watts frequency model number If watts is not on there watts= volts divided by amperes . for your estimated watts

Answer 7

Most microwaves have the wattage listed on the nameplate. Since they come in different sizes, they have different wattages, as well.

Answer 8

Seriouslly. Its 850 Watts. You answered your own question

Answer 9

they range from around 600 watts to 900 watts

Answer 10

Depends what the wattage is on the microwave
