If the voltage remains constant and the resistance doubles, the current

Explanation:
Current depends on both voltage and resistance, and with a fixed voltage the current is inversely proportional to resistance (I = V/R). If the resistance doubles while the voltage stays the same, the denominator doubles, so the current becomes half as large. In math terms: I_new = V/(2R) = (1/2)·(V/R) = (1/2)·I_original. So the current halves. This reflects that increasing resistance makes it harder for charges to flow under the same driving voltage.
