It can be operated using both AC or DC
The bulb works under AC
No. A bulb can run a AC just a easily as DC.
The voltage source that is applied to them is the difference between AC and DC light bulbs.
If its a triangular wave, its not DC, its AC, its just not sinusoidal. Can a transformer operate on triangular AC? Yes, but not as efficiently as on sinusoidal AC.
ac current
AC...
we can check the dc with the help of tester give the reasonAnswerThere is no such thing as an 'AC light bulb' and a 'DC light bulb'. A light bulb doesn't care whether it is subjected to AC or to DC.
An AC-DC converter you can operate a device on AC instead of batteries. ~bobbyjack~ : D
yes provided that power consumption is definedAnswerAC voltages are expressed as root-mean-square values, which are exactly equivalent to the corresponding value of a DC voltage. So a, say, 120-V incandescent lamp would operate at exactly the same brightness whether connected to 120 V (AC) or 120 V (DC). So, there is no such thing as a 'DC light bulb'!
A halogen bulb works equally well with AC or DC.
yes..it works
The basic fluorescent light fixture is AC, although there are fluorescent lights powered by DC.
