allow the flow of current.
stop the flow of current.
increase the flow of current.
decrease the flow of current.
Houses are wired:
in-parallel using circuit breakers.
in-series using circuit breakers.
in-series using fuses.
in-parallel using fuses.
Like charges _______, while unlike charges ________:
repel, attract
attract, repel
repel, repel
attract, attract
Assume that Circuit II is a flashlight. What would it mean if the voltage was actually supplied by two D cell batteries instead of two AA batteries?
The flashlight would have less total energy, so it would shine dimmer.
The flashlight would have more total energy, so it would shine brighter.
The flashlight would have the same total energy and brightness, but it would only last half as long.
The flashlight would have the same total energy and brightness, but it would last twice as long.
There will be a series of questions regarding this diagram. Make sure you can label it and understand its functionality.
I can tell you anything and everything you want to know about either circuit!!
I never filled out my notes
I have no idea what is going on in this class
We never talked about this in class
