Question

Nina is working with electricity and shortens the wires through which the current is flowing. What is Nina most likely trying to accomplish?

convert electric energy to heat
convert electric energy to light
increase resistance
decrease resistance

Answer 1

When Nina shortens the wires through which current is flowing, she is most likely trying to **decrease resistance**. Shortening the wires reduces their length, and since resistance is directly proportional to the length of the conductor, this leads to a decrease in resistance.
