Which appliances use more or less electricity: a 114 w fridge, a 2400 w kettle, a 850 w microwave, and one kW spiral or a solid hotplate?
The easy way to determine “how much electricity” a device uses is do not just rely upon the instantaneous wattage consumed (114, 2400, 850, and 1000 Watts, respectively), but how long (in hours, for example) the device is consuming the power. That will be the actual kiloWatt/hour measurement, which is how you pay for your electricity, and is the measurement of what you really use. For example, although the refrigerator is plugged in 24/7, it only operates and uses current when the compressor is running (or the door is open and the light is on, but that is often only 40–60 Watts for the minute or so of searching about for the goodies). When the refrigerator is humming, then it is using most of the power, which may be only a few tens of minutes in a day (depending on how efficient it is, how well insulated, how frequently the door is opened, etc.). The 2400 Watt kettle is using its power only when it is plugged in, turned on, and heating the water, for however long that takes. A microwave is similar. Only when it is heating food (or the door is open like in the case of the refrigerator) is it consuming power. So, too, is the hotplate. In all cases, some appliances may consume minute amounts of power for automatic controls (digital temperature controllers, clocks, and timers), but that is generally rather small; on the order of a Watt or two, but 24 hours a day, nonetheless.
Which consumes more electricity? tv or laptop?
Hi ! A tv , say a 25" color, uses around 150 Watts power ... Where as a laptop , it consumes around 50-60 watts power from line when it is off and charging, remember , during giving backup, it costs you nothing ... It gets charged in 3-4 hours ... But Tv runs even more ... Hence, tv consumes more power ...
Do gasoline cars use more electricity than electric cars?
The stat you see most often is that it takes 6kWh to refine a gallon of gas/petrol, which is enough to drive a typical EV for about 20 miles. An ICE car isn't going to get much further than that by burning the fuel, so those unsustainable resources are effectively being consumed to very little benefit.The 6 kWh electricity to refine gasoline would drive an electric car the same distance as a gasser? It's even worse when you consider the effort expended in prospecting, extraction and delivering the fuel. It doesn't cost the Saudis much to pull it out of the desert but the cost of extracting fossil fuels from deep sea fields or by fracking is much higher. When you take into account the full cost of producing the fuel and then burning it, it's obvious that an EV can be driven for many times the distance than an ICE for the same resource. And depending on how you generate the electricity (eg. hydro, nuclear), there may not be any carbon emissions at all involved in operating an all-electric vehicle.Internal combustion engines really are very wasteful.
Does using a small lamp use up less electricity than a Light that lights up the whole room?
Its not about lamp or ceiling light - it's about the Watts the globe in either uses. All globes have the number of Watts they use written on them somewhere. Generally in houses they range from 20 Watts up to 600 Watts. The higher the Wattage the brighter the light and the more it costs to have on. The average ceiling globe is generally 60 or 75 watts and lamps generally have 40 or 60 watts although some as low as only 15 watts. If both have the same Watt globes they each cost the same to have on. Bottom line is check the Watts of the globes - lowest Wattage least brightness, cheapest to run. The latest trend is to change to compact Fluro globes which give brighter light at lower Watts. For example a 40Watt Fluro puts out the same amount of light as a conventional 75Watt globe but costs at 40 watts because it is a 40 Watt globe. If your ceiling light has two 60 Watt globes it means you are using 120 watts total. Three is 180 Watts and so on. So its all about how many Watts. Your hair dryer uses 2000Watts. PS - lamps should have a safe maximum limit of the Wattage globe that can be used because the higher the wattage the more heat it puts out so for that reason they are generally lower to reduce the chance of a fire.
Does it use more electricity when running both washer and dryer?
My husband and I have an ongoing debate. He says it uses more electricity when I run the clothes washer and dryer at the same time. I say it uses the same amount as it does to run them one at a time.
What uses more electricity a night light or regular light bulb?
A regular light bulb uses much more. Most night lights are rated at 5-7 watts. While a normal incandescent bulb usually ranges from 40-120 watts.
Which uses more electricity: Mini Christmas lights or a light bulb?
I'm moving into a new home and my room doesn't have any electrical light source. So I've been wanting to decorate my room with mini Christmas lights for a while and I'm wondering, what uses more electricity and energy: mini Christmas lights or regular ole lightbulbs. I'm thinking maybe 4-6 strands will do the trick. Also, does anyone know how many amps a strand of mini Christmas lights draw as opposed to regular room lights?
