400
The law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.

500
Current flows best through materials known as these.
What are conductors?
600
Coulomb's law works similarly to this other universal law in its proportions.
What is the law of gravitation?
600
This is the directions that electrons move around a circuit from one terminal to another.
What is from the negative terminal to the positive terminal?
600
This is the voltage across the ends of a wire coil in a circuit if the current in the wire is 0.25 A and the resistance is 36 Ω.
What is 9 volts?
600
True or False. Adding more resistors to a parallel circuit will result in LESS overall resistance.
What is TRUE?
Explanation: Since there are multiple pathways by which charge can flow, adding another resistor in a separate branch provides another pathway by which to direct charge through the main area of resistance within the circuit. This decreased resistance resulting from increasing the number of branches will have the effect of increasing the rate at which charge flows (also known as the current). It's like opening more tollbooths at a tollway. It is more places for cars to stop but ultimately allows more cars through.
600
Current has a directly proportional relationship to this factor.
