Dates back to the days of accumulators where each cell produced1.5 volts. Adding cells in series made 3,6,12 and 24 volts easy to produce. 12v is the standard for the light automotive industry becauses it is the best voltage level to economically provide sufficient current to power things, using the smallest cables. The more items you can produce that operate from a single voltage the cheaper they become. That means, for example, that just four types of headlamp bulb will fit the majority of motorcycles, cars and light vans in the whole of the world.

Can the 2.2 microfared 250V capacitor be charged with 12V dc source?
Yes. The 250 voltage is a not-to-exceed rating.
How many volts does a computer monitor use?
from the wall it could be 115v ac, or in non American countries that use it 230v ac. internal voltages range from 12v dc, 5v dc, 3.3v dc.
What is 12v 18ah battery?
12v means it is suitable for any 12v dc current purpose the 18ah means it has an amp hour rating of 18 its a measure of how long the battery can work from full charge until it would need to be charged again ex. the bigger the ah rating the longer you could turn the starter for before the battery would run flat
Can Charge 9v with 12v dc power?
No, not possible. The charger has to go to higher volts than the battery being charged.
Can you charge a 12v lawnmower battery with a 12v car battery?
can a 12v lawn mower sealed battery be charged with 12v battery charger use on cars
How you convert a power supply into 12v DC?
DC 12V power supply can convert 110/220V AC power source to 12V DC.
Convert 12v to 3v DC?
if you have 12v dc then you can use a 4 ohm resistor
What kind of chargers have a 12v DC output?
Battery chargers have a 12v DC output.
What resistance is needed to reduce 5V DC to 3V DC?
12v dc to 3v dc
Can you use a 12v dc 1a power supply on device that requires 12v dc 3200ma?
No, 3200 ma = 3.2 amps
What resistance is needed to reduce 12V dc to 5V dc?
7K ohm
What is the difference between 10 amp and 15 amp?
what is the diference between 12V 15A DC coil & 12V 10 amps DC coil
If your input is 6V and output is 12V then which device you use?
using dc-dc converter
Can you use a 14.4V 7.2A DC battery with an amplifier which requires 12V 5A DC?
No, you cannot.
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.
What is the voltage on a 2002 Altima cigarette lighter?
12v DC
What are the 4 types of dc voltage produced by powersupply?
12V, 5V
