Ohms law. You won't know the phase angle, but you will know the
quantity.

If you know resistance, source voltage, and voltage across the
resistance you can calculate choke impedance.

How bright the bulb looks.
> What part do I connect to the choke?
The short free end of the bulb. You wantb a series circuit so you can
have RF choke current lighting the bulb.
