Question

which is true of high resistance wires?
the shorter the wire, the more resistance it has.
the thinner the wire, the more resistance it has.
the thicker the wire, the more resistance it has.

Explanation:

The resistance formula is \(R =
ho\frac{l}{A}\), where \(R\) is resistance, \(
ho\) is resistivity (property of material), \(l\) is length of wire, and \(A\) is cross - sectional area. For a given material (\(
ho\) constant), if length \(l\) increases, \(R\) increases (longer wire, more resistance). If cross - sectional area \(A\) decreases (thinner wire), since \(A\) is in the denominator, \(R\) increases.

Answer:

The thinner the wire, the more resistance it has.
