if you have 12v dc then you can use a 4 ohm resistor
12v dc to 3v dc
DC 12V power supply can convert 110/220V AC power source to 12V DC.
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.
It is not recommended to recharge a 3V battery with a 12V charger as this may damage the battery. The voltage of the charger should match the voltage of the battery to avoid overcharging and potential safety hazards. It is best to use a charger specifically designed for the 3V battery.
no, must be 3v
Battery chargers have a 12v DC output.
How much current? Volts/Amps = Ohms. In your case Volts = 1.5
Simple use a 2.25 ohm 25watt ballast resistor;renault used them to drop the voltage for the Engine control computers.

To convert a 3V peak-to-peak (p-p) AC voltage to a direct current (DC) voltage, you would typically use a rectifier circuit followed by a smoothing capacitor. The peak voltage of the AC signal is 1.5V (since p-p is double the peak), so the average DC voltage after full-wave rectification would be approximately 1.5V multiplied by 0.9, yielding about 1.35V DC. However, the exact DC output will depend on the efficiency of the rectification and filtering process used.
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
7K ohm
