A1 LT2 Flashcards
What fundamental unit of charge was discovered by researchers studying electricity?
Electrons and protons
What does Coulomb’s law of electrostatic charges state?
Force is directly proportional to charge magnitudes and inversely proportional to distance squared.
What does electrical polarity refer to?
The charge at one point with respect to another.
How can a body receive a charge?
By friction or contact, by conduction, and by induction.
What is a potential danger caused by the accumulation of electrostatic charge?
Lightning
How does the force change when either or both of the charges is increased?
force increases
What happens when two dissimilar substances are rubbed together?
Electrons are transferred, resulting in a charge.
What is conventional current flow?
Flow of holes left behind by electrons
Negative to Positive
How does the force change when either or both of the charges is decreased?
force decreases
What happens when a charged and an uncharged body come into contact?
Some of the charge is transferred to the uncharged body.
What is formed when atoms combine to form a piece of metal?
Metallic bond
What is said of a body that possesses no charge?
Neutral
How does the force change if the distance between the charges is doubled?
force decreases to one-quarter
What happens to a neutral object’s charge when electrons are removed?
It is left with a net positive charge.
