What is an electric motor?
What is a motor?
A device that changes electrical energy into mechanical energy.
What is a generator?
A device that turns motion into electrical energy.
What is alternating current?
It flow in one direction then in the opposite direction.
How does a simple electric motor work?
It changes electrical energy into mechanical energy.
How does a simple generator work?
It changes motion into electrical energy.
What is direct current?
Electric current flows continuously with out stopping.
How might an electric train use the spinning motion produced by the motor?
It will use the spinning motion to make the train go faster.
What do simple generators and simple electric motors have in common?
They both change energy into another energy.
What is the difference between alternating current and direct current?
One flows without stopping. One flows then goes in the opposite direction.
What devices have you used today that use direct current? Alternating current?
Battery devices use direct current. Lamps use alternating
What is a electric motor?
