I have a couple questions about circuits. Let's say I have a current flowing through the circuit and then it hits a resistor. The current will obviously go down while it is in the resistor but then does it stay reduced (By the strength of the resistor) for the duration of the circuit? So in theory you could put as many resistors as you needed to reduce the current to 0? What is the relationship between the voltage on the battery and the current? A circuit with a voltage of 12 V will have that as a potential, and the current is what is actually going along the path. An example is having a highway and it's speed limit is 55 mph (It's voltage) and then the actual current is the car driving on the highway. If that is right, I do not see why you do not measure current in terms of voltage, or a % of it along the path. Like at this point on the circuit the current is 5V (out of say 12V), not 5 A. Thanks for any help.
