You wouldn't want to. The Watts are the reason why.
If you needed to power 2000 watts worth of appliances and you have a 120v system, you'd need a little under 17 amps to do it. A relatively thin 12-gauge wire will handle that much power. To power the same load with 12v current, you need 170 amps--and wire 3/8" in diameter.
The built-in transformer you speak of requires 110 volts. They're known as step-down Transformers and are a ratio of the incoming voltage. For example: a 10:1 transformer will drop 100 volts to 10 volts. If you gave it 12V you'd end up with 1.2V.
In short: No to your question.
There are many appliances -- such as Google's servers -- that are designed to run on a 12 VDC supply. Appliances designed for recreational vehicles (RVs) and boats often run on 12 VDC.
In theory, a technician with some knowledge of electronics could convert an appliance that is designed to require 110 VAC and convert it to require only 12 VDC. If you are lucky, the appliance already has a transformer and rectifier that converts input power to 12 VDC, and a technician can simply attach a 12 VDC power plug, cable, and fuse directly in to that point. In practice, you would need some system to prevent accidentally plugging the 12 VDC power plug into a 110 VAC outlet, which would probably destroy the appliance, and also prevent accidentally plugging in both the 12 VDC power plug and the 110 VAC power plug, which risks destroying the 12 V power supply.
A few devices use the AC cycle to derive a time base (50 Hz or 60 Hz), and so cannot work on 12 VDC power alone, unless you use an "inverter" that generates that frequency.
Some devices -- such as air conditioners -- require a lot of energy. Given a particular energy requirement, reducing the voltage by 1/10 means increasing the current by a factor of 10, which requires power lines with 10 times as much copper. Increasing the voltage allows us to reduce the amount of copper used -- which is one reason some automobiles have a "42 V automotive system".
What else can I help you with?
What can't we use step-up transformer to increase the voltage by producing electricity of lower voltage?
This question is not understandable. You can use a step up transformer to increase voltage; you can't increase voltage by producing electricity at a lower voltage; this will result in current flow into your generator, not current flow out (similar to operating a generator in the leading mode). Please explain further under "discuss question".
Magnetic inrush current in power transformer with waveforms?
The mgnetic inrush current is the current drawn by the transformer when power is applied to the primary winding
The current load of a transformer is the current drawn by the?
load
How do you calculate current on the primary side of a transformer only knowing the turns ratio and the voltage ratio?
The primary current on a loaded transformer depends on the secondary current, which is determined by the load. So, if you know the secondary load current, then you can use the turns ratio of the transformer to determine the primary current:Ip/Is = Ns/Np
How do you calculate maximum earth fault current?
transformer max earth fault current
Can you use number of appliances on a single transformer?
You can use multiple appliances as long as long as you don't draw more current than the transformer can supply.
What kind of electricity is used to operate your electrical appliances?
Alternating current is used to operate your electrical appliances.
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
What formula calculates the current drawn by the transformer for mains electricity?
p=r*i
What is the reason for using a neutral current transformer on a transformer?
A current transformer is primarily used at the neutral point of a transformer for earth fault protection. A neutral current transformer will measure any ground fault current which will essentially flow from the star point of the transformer. A fault-detection device other devices is connected to the current transformer and, if the fault current exceeds a certain trigger value, the fault-detection device will give a trip command to an earth-fault relay to disconnect the supply of electricity to the transformer.
What kind of energy powers your light and appliances?
Usually - but not always - electricity powers our lights and appliances.
Is appliances current or static?
I think what you're asking are "do appliances run on current (AC, DC) or static electricity. The answer is: current, of course! That's what's generated by your household plug. Static electricity is really just a difference in charges being discharged by contact, be it direct (your hand to your car) or indirect (as in, through the air).
What happens when current travels through the second transformer before entering your home?
When current travels through the second transformer before entering your home, it undergoes a further step of voltage reduction and may be adjusted for the specific requirements of the local distribution network. This helps ensure a safe and consistent supply of electricity to your home at the appropriate voltage levels for your appliances and devices.
How do you use electric appliances in Israel?
You plug the appliance into the outlet. Israel uses 220-volt household current. Any 110-volt appliances brought from abroad will need a small transformer, which can be bought in appliance stores.
Do you use static electricity in your homes or current electricity?
Current electricity is typically used in homes because it is more reliable and can provide a constant flow of energy. Static electricity, on the other hand, is not commonly used in household applications due to its unpredictable nature and limited usefulness for powering appliances or devices.
Can you use an appliance on a 110 volts when it requires 120 volts?
Some appliances, like air conditioners and clothes dryers require about twice as much electricity as most other devices, and require their own 220V supply of electricity. Your appliance will not work with only half the amount of electricity it needs. I recommend calling an electrician and having him install the appropriate plug.
What is one kind of electricity?
One type of electricity is alternating current (AC), which is commonly used in homes and businesses to power appliances and electronics. AC electricity periodically changes direction, unlike direct current (DC) which flows in one direction.
