Hi John,
You control the current with the variac. Using a bulb anywhere introduces a variable and you really don't know what is going on with the capacitors.

So it's a misconception that the variac just controls voltage and the bulb acts as a current limiting device?
No, the resistance of the load works with the applied voltage to control the current. That way you get an accurate indication of the current drawn by the load.

I believe the lamp will react faster than my hand on the knob.
Yes, low-volt and lamp introduce great uncertainty in what is going on; this is just for smoke-test.

yes, i use a 100 watt bulb, at 230 volts, when there is a fault in the equipment,
then that is just 43mA if current, further damage is averted and smoke is not let out...
