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.

What is another name for rectifier convert dc to radio waves ac?
You cannot use a rectifier to go from DC to AC. You need an oscillator.
Why do you still use both ac and DC?
Because some appliances work with ac current and some with dc current.
Does ac-dc mean it can run on battery or plug into wall?
AC - Alternating Current, same thing that comes out of a wall socket DC - Direct Current, batteries. <<>> When a device has AC/DC on its name plate, it can work off either of the two voltages. Many portable radios have this function. When the radio is plugged into AC, the voltage is transformed to the working DC voltage and then rectified to a DC voltage. When the radio is on battery operation, the radio operated strictly from the DC voltage supplied by the batteries. The change between voltages from AC to DC or DC to AC is almost instantaneously. This change over is done through an AC powered relay in the radio. When the AC held in relay looses its supply it de energizes and switches over to DC power if the batteries are in the radio. With batteries in the radio try it. Plug into the AC supply, turn on the radio that has batteries installed in it, unplug the AC supply and the radio will not miss a beat.

Does a computer use AC or dc power?
Both, in a way. Electronic components, including moth components inside the computer, need DC. However, since the power available in homes or offices is AC, a computer is designed to work with this. A computer has a power supply that internally converts AC to DC.
Is commutator used for both ac to dc and dc to ac conversion?
Yes
Is bulb operate on ac or DC?
It can be operated using both AC or DC
Can you use an ac neutral on a coil powered by dc?
A neutral line can carry both AC and DC. Just make sure that the AC or DC is unable to pass through any components connected to the neutral line.
What is the difference between ac and dc grounding?
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
What kind of current used in train?
Trains use DC currents! It's predominantly AC now but more dc in the early days. Both still in use. See DC and AC section below article-
Common parts of ac and dc generators?
There is not the big different between AC and DC generator and the common part of both of them areRotorStaterFrameMagnetic FieldBarringShaftWinding (Lap or Wave)Cable boxThe big different between both of them is the commutator and split rings which we use to convert DC to AC.
How ac change to DC?
by the use of inverter we can convert ac to dc.
