Depends.
Lamps can certainly be built to work on either AC, or DC, or both. But some lamps, particularly those with electronics in them, either a dimmable lamp, or a fluorescent lamp, may only work with one type of electricity.

Why do transformers work only work on an AC supply?
Transformers only work on ac supply because it principle is mutual induction. DC supply has constant magnitude whereas AC has alternating magnitude. so we can step up or step down current/voltage in transformer in ac only.
Do step up and down transformer only work with ac power or can you use them in dc only?
AC only. That's one of many reasons why AC is more useful (and more widely used!) than DC.
Which current does a street lamp use ac or dc?
Unless the street lamp is a self-contained, battery-operated, solar-charged model, it almost certainly would be an ordinary AC-powered light.
How does auto transformer work with DC supply?
Transformers don't work with DC supplies - they only work on AC.
Does electrical transformer use a DC or AC source?
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
If AC is replaced by DC in a fluorescent lamp circuit will the circuit work?
No.
Why does the lamp bright when connected to the AC?
why does the lamp bright when it is connected to the AC supply
Why do transformers work only work on an AC supply?
Transformers only work on ac supply because it principle is mutual induction. DC supply has constant magnitude whereas AC has alternating magnitude. so we can step up or step down current/voltage in transformer in ac only.
Transformer are used in circuits containing both dc and ac?
No transformers only work with AC.
Full form of PL Lamp?
PL is mean Plug in - Light Bulb, the most comment application is CFL (Compact Fluorescent Lamp) which require assistance components to make it work or light it up, different to incandescent light bulb, it can light up by just itself direct connect to our home electricity ac 100v to ac 240v.
Why rectifier is not used in dynamo?
rectifier is not used because of damaged of problemAnswer.Because there's no need for that since the lamp on your bicycle can still work on the induced AC power.
What are the applications of a triac?
A triac is a semiconductor-based solid state electronic switch. The main applications are those which require the electronic switching of AC circuits. The switching can go from 100% on to 100% off (or vice versa) or can allow only portions of each AC cycle to pass through, which varies the amount of power supplied to the load. That is how triac-based AC lamp dimmers work.
Do step up and down transformer only work with ac power or can you use them in dc only?
AC only. That's one of many reasons why AC is more useful (and more widely used!) than DC.
Which current does a street lamp use ac or dc?
Unless the street lamp is a self-contained, battery-operated, solar-charged model, it almost certainly would be an ordinary AC-powered light.
How does auto transformer work with DC supply?
Transformers don't work with DC supplies - they only work on AC.
Do capacitors really only work in ac alternating current?
Not only for AC. Some applications use capacitors to hold a steady charge for periods of time.
What happen if 230V AC bulb is connected to 110 V DC?
A lamp will only operate at its rated power at its rated voltage. So if you connected a 230-V lamp to a 110-V supply, its brightness would be very low. It does not matter whether the supply is AC or DC; a lamp would have the same brilliance at 230 V (AC) as at 230 V (DC).As a rule of thumb for fixed-value resistances, a 10% drop in voltage results in a 19% drop in power.
