Answer / debojyoti ghosal
Fluorescent lamps can run directly from a direct current (DC) supply of sufficient voltage to strike an arc. The ballast must be resistive, and would consume about as much power as the lamp. When operated from DC, the starting switch is often arranged to reverse the polarity of the supply to the lamp each time it is started; otherwise, the mercury accumulates at one end of the tube.

no because inductive reactance is zero
Is This Answer Correct ? | 3 Yes | 13 No |
no.because the density of the filament of the fluorescent
lamp is very high for the DC supply.hence DC voltage will
not glow the lamp
