How many kilocalories of heat does the operation of a 1200-W hair dryer produce each second?
The heat produced by a 1200-W hair dryer can be converted to kilocalories by multiplying the power in watts by the conversion factor of 0.001 kcal/s per watt. Therefore, 1200 W hair dryer would produce 1.2 kilocalories of heat each second.
What is the power rating of a hair dryer?
Around 750watts but I cannot be sure it will be different with every make.
What did the first hair dryer look like?
The first hair dryer was a large, heavy and bulky contraption that resembled a vacuum cleaner with a hose attached. It required a lot of power and took a long time to dry hair.
How long does hair dry with the hair drier?
The amount of time it takes to dry hair with a hair dryer can vary depending on the length and thickness of your hair, as well as the heat and speed setting of the hair dryer. On average, it typically takes about 15-30 minutes to fully dry hair with a hair dryer.
What is the resistance of a 1100 W 120V hair dryer?
The resistance of the hair dryer can be calculated using Ohm's Law, which states resistance (R) equals voltage (V) squared divided by power (P). Plugging in the values, the resistance of the hair dryer is approximately 13.09 ohms.
How many kilocalories of heat does the operation of a 1200-W hair dryer produce each second?

How much does it cost to use a hair dryer for 30 minutes?
The price of electricity is usually quoted per kilowatt-hour. If your hair dryer uses 2,000 watts for 30 minutes, that is one kilowatt-hour.So take the wattage rating of your hair dryer and divide by 1000 to get kilowatts. You specified 30 minutes, which is 0.5 hours; multiply the kilowatts by the hours to get kilowatt-hours. Then multiply the price per kilowatt-hour of your electricity to get the total cost.For example: 1500-watt hair dryer for 30 minutes at $0.12/kW-h1500 watts ÷ 1000 = 1.5 kilowatts30 minutes = 0.5 hours1.5 kilowatts x 0.5 hours = 0.75 kW-h0.75 kW-h x $0.12/kW-h = $0.09
How many kW does a microwave use?
A hair dryer uses about 1 kW, a tumble dryer uses 3 kW.
What determines whether a 100 watt light bulb costs more to use than a 1200 watt hair dryer costs to use?
The cost to use a device depends on its power consumption (wattage) and the time it is used. The 1200 watt hair dryer will cost more to use if it is used for a longer period of time compared to the 100 watt light bulb. Additionally, the cost of electricity per unit consumed (kilowatt-hour) will also affect the overall cost.
What determines whether a 100-w light bulb cost more to use than a 1200-w hair dryer?
The cost of using a 100-watt light bulb versus a 1200-watt hair dryer is determined by their power consumption and the duration of use. While the hair dryer uses significantly more power, its operational time is typically much shorter than that of a light bulb. To compare costs, you would calculate the energy consumed (in kilowatt-hours) for each device based on their wattage and usage time, then multiply by the cost per kilowatt-hour from your electricity provider. If the hair dryer is used for a very short period, it could still end up costing less overall despite its higher wattage.
How much power does the CHI Turbo Hair Dryer use?
A CHI Turbo Hair dryer is a 1300 watt electric hair dryer. With this it dries hair up to 40% quicker than other hair dryers of it's type. Powerful and popular.
What is the power rating of a hair dryer?
Around 750watts but I cannot be sure it will be different with every make.
How many watts does a hair-dryer use?
It depends on the model, if the hair dryer is a 1500 watt hair dryer, then it uses 1500 watts on high heat. If the hair dryer is a 2000 watt hair dryer, then it uses 2000 watts on high heat. Hair dryers come in all different size wattage, so it depends on the size wattage of the dryer. Most hair dryers are 1500 watts.
How many kilowatts does a revon hair dryer per hours?
No device uses "kilowatts per hour". A watt or kilowatt is a unit of power, not of energy. That means that the "per hour" or "per second" is already implied - the watt refers to a "rate of energy conversion" - not to an amount of energy. If a devices uses a certain amount of kilowatts, it uses this amount all the time while it is on - whether it is kept on for a second or for several days.
What did the first hair dryer look like?
The first hair dryer was a large, heavy and bulky contraption that resembled a vacuum cleaner with a hose attached. It required a lot of power and took a long time to dry hair.
What determines whether a 100-W light bulb costs more to use than a 1200-W hair dryer costs to use?
The electric power used by an appliance is the rate at which the appliance converts electrical energy to other forms of energy. The electrical energy used by an appliance depends on the power of the appliance and the length of the time it is used.
