In a neon tester, how does the body complete the circuit even when it's insulated from the ground by footwear and the bulb glows?
I mean is current flowing to the neon bulb?

    Capacitive connections. – Andy aka Nov 23 '20 at 18:57

    Do you know the equivalent circuit of the tester or the hand and the body or how a capacitor works? The body is a massive dielectric with distributed resistance internally and on the surface (skin) with salty ions. Yet it only needs a tiny part in series from the hand to couple it to the common ground path through the floor and your feet which have high resistance yet a certain capacitance of water dielectric (Dk=80) due to the surface area of your hand and feet and the small gap. – Tony Stewart EE75 Nov 23 '20 at 19:38
