A hair dryer is plugged into the outlet. The outlet has a voltage of 120 Volts. If the hair dryer has a resistance of 360 Ohm's, what is the current running in the circuit?
3 Amps
0.33 Amps
43200 Amps
480 Amps
What will happen to the current in a series circuit if the resistance is increased while the the voltage remains constant?
The current will increase
The current will stay constant
The current will decrease
If you connect more light bulbs in a series circuit to a with a battery, what happens to the brightness of each bulb as you add more bulbs?
The light bulbs will remain at the same brightness
The light bulbs will glow brighter
The light bulbs will glow dimmer
What is the basic difference between series and parallel circuits?
Series circuits are not used in electrical devices; parallel circuits are used in all electrical devices
In a series circuit, there are multiple paths for the flow of charge; in a parallel circuit, there are only two paths.
A series circuit contains one path for the flow of charge; a parallel circuit contains more than one path.
A series circuit obeys Ohm’s law; a parallel circuit does not obey Ohm’s law.

protons
neutrons
nuclei
electrons
