SUMMARY
In circuit theory, the current flowing through a resistor remains constant, meaning that the amount of current entering one end of the resistor is equal to the amount exiting the other end. However, the voltage, or potential difference, across the resistor decreases as you move through the circuit. This drop in voltage is a fundamental characteristic of resistors, which can be quantified by Ohm's Law. Understanding these principles is essential for analyzing electrical circuits effectively.
