A simple electrical device is a 60 watt light bulb. The bulb is consuming 60 watts of electricity from the moment you turn it on. If you keep that light bulb on for 10 hours the power used is 60 watts x 10 hours = 600 watts of power. Electricity is sold in Kilowatt Hours. A Kilowatt is 1000 watts of power. Depending on the state you live in, it sells for 7 to 18 cents per Kilowatt Hour. So if you leave that light bulb on 10 hours per day for 30 days you will have used up 600 watts x 30 days = 18,000 watts of electricity = 18 Kilowatt Hours. At an average cost of 10 cents per Kilowatt Hour that bulb costs you $1.80 per month to leave on. The formula is watts x time x cost per Kilowatt Hour = cost of use...Answer provided by Gene Evangelist

How do you compute electrical energy consumption?
To compute electrical energy consumption, you multiply the power consumption of the device in watts by the time it is used in hours. The formula is: Energy Consumption (kWh) = Power (W) x Time (h) / 1000. This will give you the amount of energy consumed in kilowatt-hours.
A researcher determined the amount of electrical energy entering a toaster?
The researcher likely used a device called an energy meter or wattmeter to measure the electrical energy entering the toaster. This device measures the power consumption of the toaster over a period of time, which can then be used to calculate the total energy consumption. The unit of electrical energy is typically measured in kilowatt-hours (kWh).
What is the rate at which an electrical device converts energy from one to another?
The rate at which an electrical device converts energy from one form to another is known as its power consumption. This is typically measured in watts and indicates how much energy the device is using per unit of time.
How do you work out how much energy is transferred by an electrical device?
You can calculate the energy transferred by an electrical device using the formula: energy (in joules) = power (in watts) × time (in seconds). Simply multiply the power consumption of the device in watts by the time period it is operating in seconds to determine the energy transferred.
How do you compute for the cost of energy consumption per applliance?
Appliances usually have the consumption (Watts) noted on the device. If not: You can buy a device for indicating the power consumption, it fits in the wall socket, then plug in the device and note the reading. Electricity is normally charged by the Kw - hour Say the reading is 800 watts (microwave) = 800 / 1000 = 0.8 Kw Multiply by time in use (hours) Say 10 minutes = 10 / 60 = 0.167 hours Then: 0.8 Kw * 0.167 hours = 0.133 Kw - hours Multiply this by your suppliers rate per Kw - Hour, thats the cost.
How do you compute electrical energy consumption?
To compute electrical energy consumption, you multiply the power consumption of the device in watts by the time it is used in hours. The formula is: Energy Consumption (kWh) = Power (W) x Time (h) / 1000. This will give you the amount of energy consumed in kilowatt-hours.

How do you calculate consumption as percentage of GDP?
if gdp is 719.1 and consumption is 443.8, how do i compute consumption as a percentage of gdp?
What is reduction in electric consumption?
It is the reduction of using electrical devices. Each device is rated in watts. Cutting back on the use of these devices will reduce the watt consumption that is metered at the utility meter. The reduction of electrical wattage consumption will result in a savings of money to you.

What percentage of the total intermittent device load is added to the continuious duty device load to compute the total system electrical load requirement?
It depends. In the organisation I work with, we use about 30%. It could be between 20 - 50%.
How do you work out how much energy is transferred by an electrical device?
You can calculate the energy transferred by an electrical device using the formula: energy (in joules) = power (in watts) × time (in seconds). Simply multiply the power consumption of the device in watts by the time period it is operating in seconds to determine the energy transferred.
