Definitions
A small ‘package’ of light energy that acts like a particle.
What is a photon
The first principle that governs electromagnetic force.
What is all electric charges attract or repel one another?
A circuit that does not have a complete connection between the two sides of the power source.
What is an open circuit?
A cluster of many atoms that have their magnetic fields aligned and so act as a magnet.
What is a magnetic domain?
As protons flow through the coil of an electric burner, the resistance of the metal produces heat and light.
False, as electrons flow...
A buildup of electrical charges within or on the surface of a material.
What is static electricity?
The second principle that governs electromagnetic force.
What is the force between 2 charged objects is directly proportional to the amount of charge on each object?
These are the two types of circuits.
What are and series circuit and a parallel circuit?
The force a magnet exerts on another magnet, on metals, or on moving charges.
What is magnetic force?
If you want to give an object positive change, but the only source you have is negative. You would be charging the object with induction.
True.
The amount of charge that travels past a fixed point in an electric circuit each second.
What is electrical current?
The third principle that governs electromagnetic force.
What is the force between 2 charged objects is inversely proportional to the square of the distance between them?
In what type of circuit will one burnt out lightbulb cause all others to stop working.
What is a series circuit?
Because Magnetic poles always come in pairs, they are called this.
What are dipoles?
Each metal resists electron flow differently, therefore each metal has its own resistance.
True.
Current that flows from the positive side of the battery to the negative side of the battery.
What is conventional current?
This man is referred to as the founder of modern Physics.
Who is James Clerk Maxwell?
A circuit that does not have a complete connection between the two sides of the power source, as a result, current does not flow.
What is an open circuit?
What are the north pole and the south pole?
Modern Christmas lights are made using a series circuit.
False, they use a parallel circuit.
Materials through which electrons can easily flow.
What are electrical conductors?
This is the effect of a charge on other charges in the space around it.
What is electric field?
This type of circuit allows for continued electron flow with an open switch.
What is a parallel circuit?
A compass does this because it aligns with Earth's magnetic field.
Why does a compass point north?
Suppose you have two wires lying side by side. In one wire, the current flows one way, and in the other wire, an equal amount of current flows the opposite way, you could wrap those wires around a nail and make a magnet.
