100
Connect the wires of the commutator.
What are brushes?
100
A path that electricity takes or follows.
What is an electric circuit?
100
Generated by charged particles in motion.
What are magnetic fields?
200
The general rule to tell how far away lightning is after you see a flash.
What is 5 seconds per mile?
200
The rate that electric charges move through a conductor. Measured in amperes.
What is electric current?
200
Makes the current change directions every time the armature makes half revolution.
What is commutator?
200
A device used to stop/start the flow of electricity.
What is a switch?
200
A long wound coil of insulated wire.
What is a solenoid?
300
The buildup of electrons due to friction.
What is static electricity?
300
1. Like charges repel 2. Unlike charges attract each other
What is charge interactions?
300
Functional part of the motor that spins.
What is the armature?
300
electrons have only one path to follow.
What is a series circuit?
300
A force of attraction or repulsion between like and unlike poles.
What is magnetism?
400
A positively charged particle in the nucleus.
What is a proton?
400
Has a positive terminal and a negative terminal. Converts chemical energy into electrical energy.
What is a battery?
400
A device that converts electrical energy into mechanical energy or movement.
What is an electric motor?
400
electrons have more than one path to follow.
What is a parallel circuit?
400
The strongest part of the magnet where magnetic field lines are the closest.
What are magnetic poles?
500
Lightning that strikes in advance of a thunderstorm, does not need clouds.
What is arc lightning?
500
Measures how much a substance opposes the flow of electricity. Measured in ohms.
What is resistance?
500
Defines electricity. Has a negative charge and orbits the nucleus of the atom.
What is an electron?
500
An electrical device that contains a metal strip that melts to prevent overload, when current becomes to strong.
What is a fuse?
500
A strong magnet created when a metal core is inserted into the center of a current carrying solenoid.
