Question
which is true of high resistance wires? the longer the wire, the lower the resistance. the shorter the wire, the higher the resistance. the longer the wire, the higher the resistance.
The resistance formula is \(R =
ho\frac{l}{S}\), where \(R\) is resistance, \(
ho\) is resistivity (a property of the material), \(l\) is the length of the wire, and \(S\) is the cross - sectional area. When other factors (\(
ho\) and \(S\)) are constant, resistance \(R\) is directly proportional to the length \(l\) of the wire. That is, as the length \(l\) increases, the resistance \(R\) increases.
