In the following practices, the resistance of the resistance wire is increased by () A. The Resistance wire is lengthened B. The Resistance wire is folded C. The Resistance wire is cut off for A Section D. increase A. after the conductor is lengthened,The length of the conductor increases, while the cross-section area decreases,The resistance of the conductor increases;Therefore, A correct;B. After folding,The length of the conductor is reduced,The cross-section area increases,The resistance of the conductor is reduced,So B error;C. cut off the resistance wire for a while,The length of the resistance wire becomes shorter,Resistance is reduced,Therefore, C error;D. after increasing the voltage at both ends of the resistance wire,The material, length and cross-section area of the resistance wire are unchanged,The resistance remains unchanged,So D error;
A wire, cut more than half of it for the first time, and cut more than half of the wire for the second time. as a result, there are still 3 meters left.
