How does electric current affect voltage drop through a resistor?
Answers
Let us say there are two separate, independent circuits, I will not make these circuits complicated in order to thoroughly understand the question, both of these circuits are powered each of their own 12V battery, the connecting wires of both are resistance-less for these purposes, the first circuit has one 5 ohm resistor and the second with one 1 ohm resistor; now if voltage can be thought of as a measurement of the relative energy of a charge and that since theses charges are forced to do work when passing through a resistor, energy or voltage is clearly lost when a charge moves through a resistor and since the strength or length of the resistor should determine the amount of energy lost, then the voltage drop through the 5 ohm resistor should be greater than the 1 ohm resistor, the voltage drop is in fact an equivalent -12V; this can be easily compensated for with the fact that the current increases as the total resistance decreases and through the equation V=IR that an increase or decrease in current is responsible for an equivalent voltage drop of -12V, however, it is clear how the magnitude resistance can affect the voltage drop through a resistor since the resistor itself forces the charges to lose energy, but I do not fully understand how the magnitude of an electric current can physically affect voltage drop through a resistor.
