100
The smallest particles that make up all matter are called this.
What is atoms?
100

This is a complete, closed path that electric charges flow through.

What is an electric circuit?

100
Magnets are attracted to objects made of one of (or a combination of) these 3 materials.
What are iron, nickel, or cobalt?
100
This is the interaction between electricity and Magnetism.
What is Electromagnetism?
100

The total resistance of a series circuit with a voltage of 18 and a current of 8

What is 2.25 ohms?

200
This is a material that charges travel through more easily. (like metal)
What is an electrical conductor?
200

In a series circuit, what will never change, whether it is the total, or the amount at each resistor.

What is the current

200
This is one of the ways that you can demagnetize a magnet.
What is drop it/ hit it against something/increase the temperature?
200

This is a device that measure electrical current. It is often used by electricians, and may also be found in car gauges.

What is a galvanometer?

200

If there is a total voltage of 16 volts, and three resistors in series, with a resistance of 11, 12, and 17.  What is the total current of this circuit?

What is .40 amps

300

Of the 3 ways to charge an object, this way involves electrons that are being "wiped" form one object to another - like from someones hair to a balloon. 

What is friction?

300

What are the 3 necessary parts of a circuit?

What are the energy source (voltage), wires (conductor) , and load (resistors)?

300

The three types of magnets discusses

What are horseshoe, disc, and bar magnets?

300

This current travels in one directions, and is generally produced by a battery.

What is direct current?

300

A series circuit has two 9 volts batteries and three resistors.  One resistor is 4 ohms, one is 8 ohms, and the last one is 10 ohms.  What is the voltage drop at the 8 ohms resistor?

What is 6.55 volts?

400
This is the electric charge at rest on an object.
What is static electricity?
400
This kind of circuit has all parts connected in one loop. When one load doesn't work, the entire circuit fails.
What is a series circuit?
400
The region around a magnet where magnetic forces happen is called this.
What is a magnetic field?
400

A device that will convert mechanical energy into electrical energy.

What is a generator?

400

The ammeter has a reading of 5 amps at each of the 6 resistors, and each resistors has a measurement of 10 ohms.  What is the total voltage of the circuit?

What is 300 volts?

500
This is the loss of static electricity as charges move off of an object.
What is electric discharge?
500
This type of circuit is where loads are connected side by side (or in multiple loops).
What is a parallel circuit?
500
These tiny particles are found in the atoms of every object that can be magnetized.
What are domains?
500
This is a device that converts electrical energy into mechanical energy.
What is an electric motor?
500

An ammeter reads 5 amps at each of the two resistors, connected to a 24 volts battery.  One resistor has a resistance of 1.7 ohms and the other is not known..  What is the resistance of the second resistor?

What is 3.1 ohms?
