When current flows through a resistor, what effect does it have on the current?

When current flows through a resistor, it experiences a decrease in magnitude due to the resistance provided by the material. According to Ohm's law, which states that the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R), the presence of resistance means that for a given voltage, the current must decrease in proportion to the amount of resistance in the circuit.

When current encounters a resistor, some energy is dissipated as heat due to the collision of charged particles with the atoms in the resistor. This energy loss results in a drop in current as it flows through the resistor. As such, the correct understanding is that the resistor impedes the flow of current, leading to a decrease in its magnitude rather than maintaining, increasing, or disrupting the flow entirely.
