The correct response is:
The resistor decreases the current by transforming electrical energy into different types of energy.
In an electric circuit, a resistor limits the flow of electric current. When current passes through a resistor, electrical energy is converted into heat (and sometimes light), effectively reducing the overall current in the circuit based on Ohm's Law (V = IR), where increasing resistance (R) leads to a decrease in current (I) for a given voltage (V).
