Question on: JAMB Physics - 2000
A gas would serve as an electrical conductor under
A
reduced pressure and high current
B
increased magnetic field
C
reduced pressure and reduced potential
D
exposure to visible light
Ask EduPadi AI for a detailed answer
Correct Option: 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.
