Electric Charge and Force Flashcards
What is Electric Charge?
An electrical property of matter that creates electric and magnetic forces and interactions.
How do Opposites and Likes act towards each other?
Like charges repel and opposite charges attract.
What does an object’s Charge based on?
The imbalance of an object’s protons and electrons.
What is the SI Unit for Charge?
The coulomb, C.
What is the common Cable made of?
A thin copper wire in the middle for conduction that is surrounded by plastic for insulation (for safety).
What is Electric Force?
The force of attraction or repulsion between objects due to change.
What does the amount of Electric Force in something depend on?
It depends on the charge and distance of the objects.
What is an Electric Field?
A region off space around a charged object that causes a stationary charged object to experience an electric force.
What are the two types of Charges?
Positive and Negative.
What Charges do Protons, Neutrons, and Electrons have?
Protons are positive, Electrons are negative, and Neutrons are neutral.
What is an Electrical Conductor?
A material in which charges can move freely and carry a consistent electrical current.
What is an Electrical Insulator?
A material that doesn’t transfer a current easily.
What is an example of an Electrical Conductor?
A metal like copper.
What are some examples of Electrical Insulators?
Plastic and rubber.
What is built up energy called?
Static Energy.
