Two objects have collected static electricity with the same charge. What would the objects do when placed near each other?
repel
attract
nothing
stick together
As the voltage across the capacitor changes what happens to the capacitor?
There is a direct relationship between the voltage and the charge stored on the capacitor.
The electric potential energy stored in the capacitor changes by the square of the change in voltage.
Both A and B
Neither A nor B
A person combs her hair static electricity is sometimes generated by what process?
Contact when between the comb and hair results in a charge
Friction between the comb and hair transfers electrons
Deduction between the comb and hair
Induction between the comb and hair
What is the meaning of the term "resistance" as applied to electricity? Resistance is a measure of a material's opposition.
Voltage
Movement of protons
Current
Electric force
Why would a comb that had been run through hair touch one cheerio and cause the two Cheerios to come together. The comb had...
a negative charge
a positive charge
a different charge than the Cheerios already had
the same charge as the Cheerios already had
When performing an experiment with electricity, which material would act as an insulator?
staple
popsicle stick
wire
paper clip
Which statement explains why will make the balloon stick to a wall?
Rubbing the balloon on your hair creates a temporary magnet.
The balloon gets static charge when rubbed on someone’s hair.
There is glue on the wall
It is a magic trick.
How can you tell when static electricity has been discharged?
Heat is released that can be felt.
Light is released and you can feel a shock.
Static electricity gives off many different colors.
The object begins to spin rapidly when it is shocked.
A capacitor is an electrical device that
Measures electrical energy
Stores electric charge
Measure electrical conductivity
Stores electric potential
What will happen if you add more batteries to an electrical circuit containing light bulbs?
There is no change
The bulbs will dim
The bulbs will be brighter
The bulbs will last longer.
