What is an insulator?
400
This is the symbol for a light bulb.
What is a circle with an X?
400
A magnetic field is created by doing what with a wire.
What is running an electric current through it?
400
This type of circuit only has one path. So if something is not connected, the electricity will not flow.
What is a series circuit?
400
An electromagnet rotates by the poles of a magnet.This causes the opposite poles of the magnet to attract and the same poles of the magnet to push away.The coil then rotates creating electrical energy. Electric motor or electric generator?
What is an electric motor?
400
This type of generator has an alternating current.
What is an AC generator?
500
This is symbol for a buzzer.
What is a bowl with legs?
500
An electromagnet consists of these three items.
What is wire, power source and iron core?
500
This type of circuit has more than one path for the electricity to travel.
What is a parallel circuit?
500
Coils of wires are stationary while iron core rotates between magnets. An iron core is connected to a turbine that rotates by water, wind or steam. Electric motor or electric generator?
What is electric generator?
500
The magnetic field generated by a simple length of wire compared to a magnetic field generated by a coil of wire is weaker, stronger or the same.
What is weaker? The simple length of wire is weak. A coiled wire has a stronger magnetic field.
