follow is a …..
A continuously flowing closed loop is
a…
What is copper?
What is electric
current?
What is decreases?
What is parallel
circuit?
What is a circuit?
A circuit that has only one path
for the current to follow.
The build up of static
charge on a object
How much electric
energy is in an object
Which of the following is a device designed to open
an overloaded circuit and prevent overheating?

The rate at which an
electrical device converts
energy from one form to
another is called….
What is a series circuit?
What is static charge?

What is a circuit breaker?
What is electrical power?
Heat from the sun moves
through space by the
process of ….?
An example of a
longitudinal wave is
a _________ wave.
Classrooms with carpet are quieter than classrooms
with tile because the sound waves are __________.
Gravity on the moon is
th
the
gravity
felt
on
about 1/6
earth, this is because…?
The distance from the rest
line to the crest is called ...?
What is

massive that the earth.
What is the amplitude?
Electric companies usually sell electrical energy in
units of…
a. Watts
b. Amperes
c. Volts
d. Kilowatt-hours
These kinds of circuits
are less expensive to
make and have one path
or branch
Homes are usually wired with
these kinds of circuits and
why?
Can objects be charged by
moving protons from one object
to another?
Explain how grounding
can offer protection
from electric disharges.
What is kilo-watt
hours?
What is a series circuit?
Parallel circuits because if one
circuit goes out the rest of the
circuits will keep working
No, proton are held tightly
with neutrons in the
nucleus of an atom.
Grounding causes excess
charge to drain into the earth
which can absorb the excess
.
charge
