How is the positive feedback coupled to the input in a Hartley oscillator?

A Hartley oscillator is an LC (inductor-capacitor) electronic oscillator characterized by its tuned circuit, which dictates the frequency of oscillation. This tuned circuit uses a single capacitor connected in parallel with a tapped inductor (coil). The tap on the coil acts much like an autotransformer, providing the necessary positive feedback from the output back to the input of the active device (like a transistor) to sustain continuous oscillation. Distractors such as a 'capacitive divider' describe a Colpitts oscillator, while 'link coupling' and 'neutralizing capacitor' are techniques used in amplifier coupling and parasitic suppression, not for providing primary feedback in a Hartley oscillator.
