When the spiral coil is extended and there are gaps between consecutive components, the current rises. Reactance must drop in order for current to rise.
A wire in the form of a tightly wound solenoid is connected to a DC source, and carries a current. If the coil is stretched so that there are gaps between successive elements of the spiral coil, will the current increase or decrease? Explain.
