No, you definitely cannot.
A definite purpose contactor is designed (and rated) for a specific load. So a lighting contactor is one example of a definite purpose contactor. A motor starter contactor is another example. So, a lighting contactor is a definite purpose contactor, but a definite purpose contactor is not necessarily a lighting contactor (it might be a motor starter, for instance).
You probably mean "... where there should be a DC output ?",and the answer is "No. They don't work in reverse.".
Because some appliances work with ac current and some with dc current.
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
by the use of inverter we can convert ac to dc.

The AC systems are more readily available. All countries national grids are AC systems. With the use of transformers the voltage can be transmitted over long distances. DC systems have their place but are not comparable to the AC systems that run countries.
240v ac
Radios use DC power supplies to operate. If a radio is powered from a mains AC supply, a power supply circuit will convert the AC supply to DC. Therefore, a radio may have both a DC and an AC power input but ultimately, the internal circuitry will always use DC.

the car use dc current dear
no the dc unit will be damaged . but , if you have no other options left then you have to use a rectifier to convert the ac into dc .
AC or DC? AC - use a transformer, DC - forget it - not simple or cheap.

I would assume that you mean what devices do you use to convert ac current to dc current?The answer is Diodes.seediode-bridge
