A resistor is made out of a long wire having a length L.Each end of the wire is attached to a terminal of a battery providing a constant voltage V₀.A current I flows through the wire.If the wire were cut in half,making two wires of length L/2,and both wires were attached to the battery (the end of both wires attached to one terminal,and the other ends attached to the other terminal),what would be the total current flowing through the two wires? A) 4I B) 2I C) I D) I/2 E) I/4

When the wire is cut in half and both halves are connected in parallel to the battery, the resistance of each half is halved. Since the wires are in parallel, the total resistance is further reduced by half, resulting in a total resistance of one-fourth of the original. According to Ohm's Law (V = IR), the current is inversely proportional to the resistance, so the total current becomes four times the original current, 4I.
