1. If the distance between two charges is doubled, what happens to the electrical force between them?

Question

a. It will double
b. It will quadruple
c. It will half**
d. It will reduce by a magnitude of 4

2. Why do insulators resist the flow of electricity and heat?
a. They are made of materials that resist charges
b. They create opposing electric forces to reduce the motion of charges
c. They do not allow their valence electrons to move easily**
d. They cannot transfer heat due to their low heat capacity

3. Which of the following equations is almost identical to Coulombs Law?
a. Newton's Law of Gravitation
b. Newton's First Law**
c. The Static Friction equation
d. The Work Energy Theory

4. Why do most objects have to be charged by transferring electrons to and from the object?
a. Most objects are insulators and require manual transfer of electrons for charges
b. Friction is necessary to generate new charges in matter**
c. Most objects are electrically neutral because they have equal numbers of protons and electrons
d. Most objects have electrical imbalances that need to be corrected by transfers

5. What is the similarity between Coulomb's Law and the equation for electric fields
a. Both function only when you have multiple charges**
b. Coulomb's Law is found through a derivation of the electric field equation
c. The electric field equation can be found only in situations where Coulomb's Law is invalid
d. The electric field equation is the same as Coulomb's Law, just with only one charge

6. Where is the electric field the strongest?
a. Far away from the source charge
b. Only at one specific point in the field
c. Closest to the source charge**
d. The electric field remains the same at all locations

7. Kirchhoff's Current Law is derived from which fundamental Physics law?
a. The Law of Conservation of Mass**
b. Newton's Law of Gravitation
c. The Inverse Square Law
d. The Law of Conservation of Charge

8. Which of the following statements can be inferred from Kirchhoff's Voltage Law?
a. All of the voltage provided by the source will be used by all of the circuit elements**
b. All of the voltage provided by the source will be the product of the current and resistance
c. All of the voltage provided by the source is created by a chemical reaction
d. All of the voltage of the source must be less than the total required voltage of the circuit

9. A very common electrical hazard is plugging too many devices into a single outlet. This runs the risk of having too much electricity flowing though a single location, in this case, the primary plug.

If we assume all plugs are parallel circuits, we can use ___Coulomb's___ Law to explain why having too many plugs in a single socket would cause too much electricity to flow.
True**
False
