reduced pressure and high current
increased magnetic field
reduced pressure and reduced potential
exposure to visible light
Correct answer is A
In general, gases conduct electricity under reduced pressure and high voltage/potential.
But from Ohms Law, current is directly proportional to voltage. Thus high current presupposes high voltage.
