Things that need a battery in order to work, must need Direct Current at some point, if not all, for it to work. eg a hand torch.

Will a photocell work using dc voltage?
it creates a dc current
Why do you still use both ac and DC?
Because some appliances work with ac current and some with dc current.
How does a power inverter work?
Power inverters work as an electrical converter which allows a direct current to change into alternating current. This is the commonly known as a DC-AC power conversion. In short, inverters work the opposite as rectifiers that converts AC or alternating current into DC or direct current.
Does watt meter use for ac and dc?
No, on dc the power is measured by the produce of the voltage and current so there is no need for a wattmeter, which would not work on dc anyway.
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.

How DC generator produces DC current from ac current?
DC GERATORS PRODUCE DC current with the help of spilt ring commutators.

No, on dc the power is measured by the produce of the voltage and current so there is no need for a wattmeter, which would not work on dc anyway.
If DC is applied to the primary of a transformer is there any current in the secondary and if there is then whether ac or DC?
first, understand that a transformer is an AC DEVICE. it wont work on dc...
DC current is not used in transformer?
No. Transformers rely on the magnetic field changing direction to work, so DC can't be used.
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
Battery ac or DC?
A battery supplies DC.
How does an ac curcuit work if current cant flow through a capacitor?
AC current can flow through a capacitor, it's DC current that can't
Is electronics device only work in direct current?
Electronics devices are work both AC and DC currnt . Such as Diode , SCR , Capacitor can work both AC and DC current . Espacilly voltage control circuits such as dimmer , and then voltage rectifier circuits , means power suppy circuts and so on.
Which is the device that converts AC to DC?
A Rectifier converts Alternating current into Direct current
