Imagine your microwave is rated for 1,000 watts, which is typical for a full-size countertop model, and your electricity rate is the national average of 12 cents per kilowatt hour (kWh). At full power, that microwave will consume about . 02 kWh per minute, which will cost you about one fifth of one penny.

So how much energy does an electric stove use per hour? Assuming an electricity rate of 12 cents per kilowatt-hour (kWh), a 3000-watt oven will cost you about 36 cents per hour at high heat. As for the burners on the electric stovetop, bigger burners draw more electricity.

An electric blanket might consume 200 watts (depending on the setting). So if you leave it on for 10 hours, it consumes 2 kilowatt-hours. That would cost between 15 and 30 cents, depending on your location.

Thus - 1 (Amp) x 1 (Volt) = 1 Watt. say any Electric Appliance (May be an Electric Heater) having power of 1 Kilo Watt (i.e. 1000 watt), at Supply Voltage of 230 Volts, will draw a current = 1000(Watt)/ 230(Volts) = 4.3 Amps (aprox.) 60 Hertz in 1 Watt!

According to energy expert Michael Bluejay, a typical electric oven on medium heat uses about 2,000 watts of energy. That means running it for three hours would use 6 kilowatt-hours (kWh) of energy. Cooking the pot roast in the pressure cooker instead would cut your energy use down to around 2 kWh.

At 12 cents per kWh, a microwave that uses five watts of standby power will cost you about 44 cents per month, or $5.26 per year. That's right — the cost to power the digital clock is higher than the cost of cooking in our example, if only by about a buck and a half per year.

Consider: coal power plants provide roughly 45 percent of U.S. electricity at a seemingly bargain price — just 3.2 cents per Kilowatt hour (KWh) of electricity, or enough power to run your microwave for an hour.

The power of our toaster is 1200 watts and the times it takes to toast a piece of bread is one minute which we will convert into seconds by multiplying by 60 seconds per minute. The energy consumed will be the power multiplied by time. So that's 1,200 watts times 60 seconds, which is 72,000 joules.

Microwave Repair Costs The cost to repair a microwave is usually $70 per hour plus the price of materials. The total cost ranges from $50 to $400, averaging about $150. Most homeowners will pay $100 to $200 including labor and parts. This depends primarily on the brand, model and the broken part.

A dishwasher's base electricity usage is pleasantly inexpensive. For a 1200-watt model and a load time of one hour, you use 1.2 kilowatt-hours (kWh), which is about 12 cents per load on a 10 cent per kWh electricity plan.

Modern Slow cookers consume as little as 150 Watts per hour at Low setting. So in 6 hours on a low setting, the total use is 900 -watt-hours. This is a much lower consumption than an electric stovetop or an oven needs to get a meal cooked. Even a pressure cooker will consume much more electricity.

Multiply by hours used per day. The wattage tells you the rate energy is consumed while the appliance is active. Multiply the wattage by the number of hours the device runs during an average day. Example: If the microwave runs for half an hour each day, multiply 780 watts x 0.5 hours / day = 390 watt hours per day.

The microwave oven cooks food by using high frequency electromagnetic waves (part of the electromagnetic spectrum - so their speed is 3 x 108 m/s in a vacuum) called microwaves at 2.45 GHz. The wavelength of mircowaves are between 1 millimetre and 30 centimetres.

How much electricity does a dishwasher use and how much does it cost? Dishwashers run on electricity, and an average machine uses around 1.5 kWh to clean a typical load of dishes (around 12 place settings).

Most electric ovens draw between 2,000 and 5,000 watts, with the average electric stove wattage coming in at around 3,000 watts. So how much energy does an electric stove use per hour? Assuming an electricity rate of 12 cents per kilowatt-hour (kWh), a 3000-watt oven will cost you about 36 cents per hour at high heat.

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.
