Every electrical item draws a certain number of watts, the given unit for measuring energy consumption. If you are trying to determine how much wattage your house will pull over any period, you'll need to find out the wattage of each appliance. Each appliance can have wildly ranging wattages depending on the model, features and manufacturer, so the numbers listed here are just approximations from the U.S. Department of Energy
That depends on the appliance and what you're trying to accomplish. Low watts mean that the appliance doesn't use much energy. Higher wattage appliances may be able to complete a task faster or operating on a larger mass. Smaller wattage appliances may be all you need if you're just preparing for a smaller group or if you aren't in a hurry. +++ The overall power consumption will be the same to perform the same task.
The wattage of bulb one uses in a bedroom lamp depends on several factors. If it is a lamp used for back ground lighting or a night lamp, one would use a very low wattage bulb. If it is for a bedroom reading lamp, one would want a stronger wattage. The biggest factor on deciding what wattage to use is the wattage suggested by the lamp manufacturer. All lamps are marked with recommend bulb wattage.
A switch does not use wattage, or consume power which is a better way of putting it. It depends on what appliance is being controlled by the switch.
To calculate the amperage of an appliance use the following equation, I = W/E. Amps = Watts/Volts. In North America the home voltage for larger appliances is 240 volts. Somewhere in the oven there will be a name plate. on it will give you the wattage of the device. Divide the voltage of 240 volts into this wattage value and you will end up with the amperage that the oven requires to operate.
This is okay as long as you don't exceed the total wattage rating for the track.

use low wattage light bulbs

Low wattage bulbs have no gas, just vacuum. Higher wattage bulbs typically use nitrogen as it is inexpensive, but some may use argon.
Some appliances are better adapted to batteries based on portability. Batteries allow significant portability. Appliances that remain in place, like a refrigerator, would not need batteries.
Provided the heater is of a low wattage it should not affect normal running of the car
It depends on the appliances themselves. If you use Ohm's Law, 120 volts multiplied by 20 amps you get 2400 watts. If these appliances are constantly used at the same time it is best to calculate your loads at 80%, in this case it would be 1920 watts. Look at the name plates on the appliances, the wattage on each will be listed.
Yes, it is possible to use a grapefruit as a battery, the lightbulb has to be fairly low wattage though.
It has to do something with being eco friendly...it has to be about how you can be helpful to the environment even in your kitchen....please help me out... A green kitchen is essentially designed to be eco friendly and use energy saving appliances. For example, using low wattage microwaves, fluroscent light bulbs, energy star qualified refrigerators, etc. Energy saving appliances might cost more initially, but in the long-run will save you money and help out the environment.
since circuit breaker consists of coils they get heated up when high current flows, when this happens the coil get energised and pull the moving contacts to open thus the circuit breaker opens when high current flows.
Wattage = Outage Voltage + Outage Wattage
