Compare And Contrast Conductors And Insulators

Question: Define what electrical energy is, and provide an example of it in everyday life. (Answers Vary)

Answer: Electrical energy is energy carried by moving electrons in an electric conductor.
Ex: Phone charger

==================================================

Question: How is an electrical current like a river of water? Compare and describe. (Answers Vary)

Answer: Because the electrons are carried through the current. The river flows in one direction.

==================================================

Question: Identify what an ion is and contrast it to a regular atom (balanced or imbalanced # of protons/electrons? What kind of force?)

Answer: Ion is an atom or molecule with a net electric charge due to the loss or gain of one or more electrons. Atom is the smallest particle of a chemical element that can exist.

==================================================

Question: Compare and Contrast conductors and insulators, correctly identify materials on a chart, and give examples in real life.

Answer: Conductors are material that permit electrons to flow freely from particle to particle.
Insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule.

==================================================

Question: List insulators

Answer: Dry air
Wood
Glass
Rubber
Plastic

==================================================

Question: List semi-conductors

Answer: Germanium
Silicon

==================================================

Question: List conductors

Answer: Silver
Copper
Aluminum
Iron
Mercury
Carbon
Water

==================================================

Question: Describe how electrical energy travels through materials that is a conductor.

Answer: Conductors are materials that allow charges to FLOW through freely. Insulators are materials that halt or stop the flow of charges

==================================================

Question: Evaluate how induction results in polarization, and provide the argument as how polarization is NOT the same as electrical charge.

Answer: They can be induced into moving from one part of an object to another During induction, the positive charges and negative charges separate into opposite sides of the object This separation is called polarization

==================================================

Question: Compare and contrast the difference between current and voltage, and provide units for each.

Answer: The measure of potential energy of the electrons in a circuit.

==================================================

Question: Explain how resistance relates to current and voltage, and express it in the formula for ohms law.

Answer: The current is directly proportional to the voltage and inversely proportional to the resistance

==================================================

Question: Compare and contrast the difference between direct and alternating current

Answer: Direct current only flows in one direction, alternating current changes direction periodically.

==================================================

Question: Compare and contrast the difference between series and parallel circuitry

Answer: Series shares a common path parallel shares two
