What resistance is needed to reduce 5V DC to 3V DC?
12v dc to 3v dc
How you convert a power supply into 12v DC?
DC 12V power supply can convert 110/220V AC power source to 12V DC.
Can you recharge a 3V battery with 12V charger?
No, you can not charge a 3V battery with 12V charger.
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.
Can you use an AC adaptor - 3v dc 800 ma to replace AC adaptor - 9 v DC 250 ma?
no, must be 3v
How much resistance required to convert 12V DC to 10.5V DC?
How much current? Volts/Amps = Ohms. In your case Volts = 1.5
What kind of chargers have a 12v DC output?
Battery chargers have a 12v DC output.
How do you convert 12v DC to 5v DC?
Simple use a 2.25 ohm 25watt ballast resistor;renault used them to drop the voltage for the Engine control computers.
How much resistance required to convert 12v DC to 6v DC?
Use a 2.25 ohm 25watt ballast resistor;renault used them to drop the voltage for the Engine control computers.
Can you use a 12v dc 1a power supply on device that requires 12v dc 3200ma?
No, 3200 ma = 3.2 amps
What resistors are required to reduce 12V dc to 3V dc with a LM317t positive adjustable voltage regulator?
a there many value to choose from as long as there is at least 50 m amps of bias flowing to the adjust input. the calculation start with known factors like the regulator out put is 1.25 then the rest is just a matter of mathematics
What resistance is needed to reduce 12V dc to 5V dc?
7K ohm
