Depends what current out you want. Step-down transformer and a bridge rectifier and smoothing curcuit, or switch mode supply. Spend less than a tenner and buy a battery charger

How you convert a power supply into 12v DC?
DC 12V power supply can convert 110/220V AC power source to 12V DC.
How do you convert 24volts to 12 volts?
If you want to convert 24v AC into 12v Ac, it's simple. Just get a transformer to convert 24 volts into 12 volts. This is called a stepdown transformer. If you want to convert 24v DC into 12v DC, it's more complicated. First you have to change the 24v DC into 24v AC by a switching converter that changes DC into AC. Then you would use a stepdown transformer as in the former example. Once the 24v AC is converted to 12v AC, then you use a rectifier bridge to change the 12v AC into 12v DC.
Convert 12v to 3v DC?
if you have 12v dc then you can use a 4 ohm resistor
How do you convert 220 ac to 12v DC?
You'll probably have to have a step-down transformer to take the 220vac down to 110vac. Then you'll have to have an Ac to Dc converter box to change the Ac to Dc volts. The converter will probably have an adjustable output so that you can dial in 12vdc.
How a ballast resistor convert DC into ac?
A resistor, by itself, can not convert DC into AC.
How do you increase voltage 5v 12v?
AC or DC? AC - use a transformer, DC - forget it - not simple or cheap.
How do you increase voltage 5v-12v?
AC or DC? AC - use a transformer, DC - forget it - not simple or cheap.

How ac change to DC?
by the use of inverter we can convert ac to dc.
What type of electrical equipment cannot convert AC into DC?
A transformer cannot convert AC into DC.
How you convert DC TO ac?
we can convert a dc supply to an ac supply using inverters. Its a common operation which we observe in our daily lives dc can be converted to Ac using an undulator.
