Intro to Basics
What are two types of charges?
Positive and Negative
What is the variable for Voltage?
V
What is the metric unit for the Electric Potential Energy (Electric PE or PE el)
Joules
What is the force that prevents/slows down electric current in a circuit?
Resistance
What is materials that do not have free electrons and do not allow the flow of current?
Insulators
What is the unit of measure for electric current?
Amperes (or Amps)
What happens to the Electric PE if a positive charge moves TOWARDS another negative charge?
Electric PE Decreases
What is materials that have free electrons and do allow the flow of current?
Conductors
What is the variable for charge?
Q
What happens to the Electric PE if a positive charge moves TOWARDS another positive charge?
Electric PE INCREASES
What does Voltage provide to an electric circuit?
Power
What Law describes the strength of an Electric Force
Coulombs Law
What does the unit Ohm measure?
Resistance
What happens to the Electric PE if a positive charge moves AWAY another negative charge?
Electric PE INCREASES
What would happen to the current if resistance increased?
Current would DECREASE
Describe what the Law of Conservation of Charge states. Be Specific
Charge cannot be created or destroyed... only TRANSFERRED
(50 Bonus if you remembered what it can do)
What is the variable for current?
I
WHY is Electric PE considered to be a Field Force?
Because objects feel the force WITHOUT TOUCHING
Describe how Voltage and Current relate to each other. WHY?
With more Voltage = More Current
Voltage = Power Source (the kick)
