DC cannot be easily stepped down using a transformer like AC because Transformers work on the principle of electromagnetic induction, which requires a changing magnetic field to induce a current in the secondary coil. Since DC has a constant magnetic field, it cannot induce a current in the secondary coil of a transformer. However, DC can be stepped down using other methods such as voltage divider circuits or chopper circuits.
What else can I help you with?
CAN YOU STEP DOWN 36 volt dc to 12 volt dc using batteries?
can ou step down 36 volts dc to 12 volt dc using batteries
What is an substance that cannot be broken down?
An element is the only substance that cannot be broken down.
Why do you step up and then step down electricity from a power station?
With transformers. To answer "Why": It is more efficient to use high voltage over long distances, so the voltage is normally stepped up to standardized potentials for the journey. When it gets to your home it is stepped down to the proper potential for standardized household appliances.
What is a substance that cannot be broken down into a similar substance?
An element cannot be broken down into a simpler substance by chemical means.
How many amps is 20v dc 18v ac 35va dc max?
To convert VA to amps for DC, you can use the formula: Amps = VA / Volts. For the given values, the max DC current would be 35VA / 20V = 1.75A. The 18V AC value cannot be directly converted to amps without additional information.
Can 10kv dc power be stepped down to 12v dc power?
Not without a lot of very expensive equipment
Which country use DC supply for domestic applications?
More over the rating only differs from country to country.No country employs DC current for domestic appliances because the voltage have to be stepped down or stepped up as per our requirement.
What is the past tense of step down?
The past tense is stepped down.
Advantages of ac generators over dc genrators?
The output of an AC generator can be stepped up with a transformer. The high voltage can be more easily transferred over longer distances with higher gauge wire. At the destination, the high voltage can then be stepped back down with another transformer.
Why is an AC always positive and negative sine wave?
It is because, sine wave can be easily produced mechanically (at power stations) compared to other forms of waves. +++ Further, alternating voltage is readily stepped up or down by transformers, something you cannot do with DC, but a very important practical property of AC electricity.
Who was stepped down in the Russian revolution?
Assdf
What type of electrical equipment cannot convert AC into DC?
A transformer cannot convert AC into DC.
Who were the two junior emperors when diocletian and maximian stepped down?
The two junior emperors when Diocletian and Maximian stepped down were Galerius and Contantius Chlorus (Constantine's father).
Why direct current is not used for transission of electricity through wires?
Two reasons: 1. Alternating current does not loose as much power over long distance. 2. Alternating current can be stepped up or down through transformers, allowing AC to be transmitted at high voltage (even less current loss) and then it can be stepped back down inside your home. For short distances and if there is no need to step up or down, DC is fine.
Why is dc current not used as much as ac?
DC Current is used in the various devices we have. Assuming your talking about transmission and distribution, you can step-up AC voltage to very high values with transformers. The size of the conductor carrying that high voltage can be very small. At the destination, the high voltage is stepped back down with another transformer. You could not do any of this with DC
Why do you obtain more dc voltage than ac voltage in power supply design by using transformer?
You don't. Transformers only work with AC voltage. Their input will be an AC waveform, and their output will be an AC waveform. Other electronics are used to convert the stepped down AC waveform from the transformer to DC.
Can dc current work on transformer?
Transformer is by definition can transform only AC current. But it's possible to build device that can step up or step down DC voltage directly. These are called DC-DC converters not transformers.
