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

Explanation:

Step1: Recall the formula for resistance

The resistance \(R\) of a wire is given by the formula \(R=
ho\frac{l}{A}\), where \(
ho\) is the resistivity of the material, \(l\) is the length of the wire, and \(A\) is the cross - sectional area.

Step2: Analyze the effect of changing length

When the length \(l\) of the wire is shortened (assuming \(
ho\) and \(A\) remain constant), from the formula \(R=
ho\frac{l}{A}\), if \(l\) decreases, then \(R\) (resistance) decreases.

Answer:

decrease resistance
