Vocabulary
A closed path for electricity to travel.
What is a circuit?
The movement of electrons.
What is electricity?
The term for electric potential energy.
What is voltage?
The type of current comes from a household battery.
What is Direct Current (DC)?
The main type of current used in household electrical systems.
What is Alternating Current (AC)?
Current that always moves in the same direction.
What is direct current (DC)?
What is the difference between the flow of conventional current compared to electron movement
What is that conventional current moves from positive to negative while electrons actually move from negative to positive?
Something that transfers electric energy into a different type of energy and opposes or slows down the flow of electric current. Measured in Ohms.
What is a resistor/resistance?
The positive end of a battery.
What is a cathode?
The type of circuit primarily used in households. It contains 2 or more paths for current to move through, so that if one light goes out, the others will stay on.
What is a parallel circuit?
The force of attraction or repulsion between charged particles.
What is electrical force?
What does it mean when we say that a particular material is an insulator?
What is it means that the material does not allow electricity to move through it easily?
The movement of electric charge measured in amperes.
What is current?
A device that changes chemical energy to electrical energy.
What is a battery?
The string of lights on your Christmas tree goes out when one of the bulbs burns out. Why do all of the lights go out in that string.
What is because the string of lights forms a series circuit?
A gathering of extra electric charge on an object because electrons bind more to some substances than others.
What is static electricity?
An instrument used to detect electric charge.
What is an electroscope?
List the 3 forms of Ohm's Law.
What is V=IR, R=V/I, and I=V/R?
What does your computer's charging cord adapter do?
What is it converts the AC from the house to the DC your computer's battery requires?
Why is copper used in the wiring of modern houses?
What is because copper is a good conducting material?
This type of charging is done without direct contact between the object and a charge.
What is charging by induction?
Name the law that states that charge can move between objects but not be created or destroyed.
What is the Law of Conservation of Charge?
What happens to the current in a circuit if a 6V battery is removed and is replaced by a 12V battery?
What is the current increases (2X)?
The type of cell that uses an acid solution to generate electricity. An example is an automobile battery?
What is a wet cell battery?
The reason your household lights appear to be flickering when you take a slow motion video.
What is because in the Alternating Current in houses goes in a back and forth motion that is detectable in slow motion videos.
