In simple appliances that consist of basically just a resistor, the power is proportional to the voltage-squared, so each 1% increase in voltage gives a 2% increase in power.
That applies to an electric convector. On the other hand if it has a thermostat, it will cut out just a little sooner if the voltage is higher, so in the long run the kWh will be about the same.
Other appliances using a switch-mode power supply (e.g. computer) draw the same power when the voltage is changed (within reason).
Most electric lights draw more power when the voltage is increased.

Overvoltage can lead to increased kilowatt-hour (kWh) usage because it causes electrical appliances to operate less efficiently. When an appliance is subjected to higher voltage than it requires, it may draw more current, leading to increased energy consumption and subsequent higher kWh usage. Additionally, overvoltage can potentially damage appliances, resulting in increased energy consumption or even complete malfunction.

Calculate per unit cost in terms of kilowatt hour for electricity?
Divide the monthly billed charges from the Utility by the months usage in KWH. Monthly Bill divided by KWH (usage for month) = Unit Cost
What is the formula for computing electric consumption cost if we are given the wattage no. of hours of usage and cost per kilowatthour?
First, divide watts by 1000 to get kilowatts: watts / 1000 = kW Then multiply kilowatts by the hours of usage to get kilowatt-hours kW * hours = kWh Finally, multiply kilowatt-hours by the cost per: kWh * (cost per kWh) = cost to operate
Calculate electricity usage?
Watts x hours/1000 = Kwh Kwh x your electricity cost ($/Kwh) = $ For example: If you run a 60 watt light bulb for 8 hours and your electricity rate is $0.12/Kwh: 60 x 8 / 1000 = 0.48 Kwh x $0.12 $/Kwh = $0.576, or about 6 cents. This calculation works for any appliance, the watt usage is usually listed on the appliance
Your dehumidifier is 820 watts and 3.5 amps how much electricity does it use in 24 hours and what kwh usage?
1000 watts = 1 KW, so: 820 watts = 0.82 KW 0.82 KW * 24 hours = 19.68 KWH
What does the average kwH cost?
It is 12 cents per kwH for the US as of April 2009 New England area had the highest average around 15 cents and Hawaii came in at 22 cents Average monthly usage is 935 kwH per month for the US Here in WA state we pay 6.8 cents per kwH I am planning on going solar or wind or permanent magnent motor (when it gets perfected real soon I hope) to not pay any utilities.
How many kWhs are there in a kW?
kWh is usage, while kW is power. One kW for one hour is one kWh, one kW for 30 minutes is 0.5 kWh ASO
Calculate per unit cost in terms of kilowatt hour for electricity?
Divide the monthly billed charges from the Utility by the months usage in KWH. Monthly Bill divided by KWH (usage for month) = Unit Cost
How does voltage effect kWh?
voltage is pressure and kWh is energy... therefore pressure is energy...
What is the average kWh usage per house in the US?
The average kWh usage per household in the US is around 900 kWh per month. This can vary depending on factors such as climate, household size, and energy efficiency measures in place.

Factor on which the insulation of ehv lines depends?
it depands on switching overvoltage or lightening overvoltage.

What is the average electric bill for a 1 bedroom apartment in Milwaukee WI approx 700sq ft all appliances are electric heat is gas?
Winter, Spring & Fall electric usage 240 - 300 KWH. $35 - $40 Summer electric usage 600 KWH using air 68 - 70 Degrees F. $65 - $70 All prices may vary depending on the power company rate per KWH.
Electric energy usage on your electric bill is measured in?
Kilowatt hours.
What do kilowatt hours measure?
a kilowatt hour measures electrical usage in the home usually 600 to 1200 kwh for the average home
What is an momentary overvoltage?
Spike
Your dehumidifier is 820 watts and 3.5 amps how much electricity does it use in 24 hours and what kwh usage?
1000 watts = 1 KW, so: 820 watts = 0.82 KW 0.82 KW * 24 hours = 19.68 KWH
