How much electrical energy does electric fan with a power rating of 100 watts use in 1 hour?

It varies tremendously depending upon the size of the fan and the power of the motor. The best way to answer your question would probably be to look at the back of the fan, or on the bottom. It usually will tell how many watts the fan draws. If it only tell amps and volts, remember that watts = amps X volts. Remember that watts does not have a time component; so to say that it draws a certain number of watts in an hour is not correct. You should rather ask, "How many watt-hours does it consume in an hour?" That is the number of watts times the number of hours that it drew that number of watts.

∙ 12y agokilo-watt is unit of power and kwh is energy consumed by a fan if it runs for 1 hour
Nominal ceiling fan power (wattage) is ~100 watts = 0.1 kW
So, Should it run for an hour the energy consumed = 0.1kW*1hr = 0.1 kWh

∙ 11y agoA fan uses 40 to 80 watts of energy depending upon the speed and sweep or power of the motor. Higher the sweep, higher the wattage.

What kind of energy is stored in an electric motor?
A machine that turns electricity into mechanical energy is known as an electric motor. The rotor's inertia, as well as the mechanical system that supports the motor, stores energy. It controls the electric motor's torque and speed. It maintains a safe temperature range for the engine, power electronics, electric motor, and other components. It functions as a power source for the electric traction motor. Electrical energy is transformed into mechanical energy by electric motors.
Why are generators helpful?
Electrical generators produce electric power, and generators solve the problem of production. We use electricity in countless ways, and we need to access some kind of generator if we can't directly access the power grid.
Can you store electric power?
Yes, a battery is an electrical storage device.
Does motor rating mean the electrical power required into a motor or the electrical power of the motor's output?
Normally you would specify a motor to do a particular job by the mechanical power output you require.A motor takes electrical power "in" and produces mechanical power "out".Read whatever it says on the motor's rating plate or user-guide.The mechanical energy output of a motor is measured in various units around the world: for example in watts, horsepower (or brake horsepower).Another answerThe above answer is quite correct in stating that a motor's output power is its rated power as it's a guide to how much load it can drive.Power is simply a rate - the rate of transfer of energy. The horsepower is the Imperial unit of power, whereas the watt is the SI unit of power. In the US the output power of a motor is typically still measured in horsepower whereas in Europe the use of horsepower is almost obsolete, except for small "fractional horsepower" electric motors, and both the input power and the output power of a motor are measured in watts or, more likely, kilowatts.
What is the difference between transformer and generator and motor?
A motor is a machine that converts other forms of energy into mechanical energy, therefore creating motion. A generator converts mechanical energy into electrical energy via the method of magnetic induction. You should probably check up Michael Faraday and Lenz. Or maybe look in a HSC Year 12 text book like Jacaranda.

What energy transformation occurs in the electric iron?
Which energy transformation occurs in an electric iron
What type of energy is electric?
Electrical energy. If something needs energy from electricity to work then that energy is electrical energy. Electrical energy comes from power stations or batteries.
What is an example of nuclear energy to electrical energy?
nuclear power station generates electric
What is a equation for electric energy?
electrical energy (in kWh) = electric power (in kWh) X time (in hours) E=Pt
Where would an electric car get its power?
It depends on whether you mean electrical power or mechanical power. The electrical power comes from the on-board batteries. The mechanical power comes from the motor. The motor is what makes the electrical power turn into mechanical power this is what goes through the drive train to propel the wheels.The Electric car will get its electrical energy from the batteries. The electrical energy is then converted into mechanical energy by the motor. The mechanical energy is then transfered into the wheels providing the power needed to achieve propulsion.
