How does auto transformer work with DC supply?
Transformers don't work with DC supplies - they only work on AC.
Do step up and down transformer only work with ac power or can you use them in dc only?
AC only. That's one of many reasons why AC is more useful (and more widely used!) than DC.
Can a rectifier work on DC?
Well, yes. But it isn't much needed as DC is already DC.
Will a photocell work using dc voltage?
it creates a dc current
Does electrical transformer use a DC or AC source?
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
Do you have to connect a cell to work an electromagnet?
A cell or other (DC) power source must, indeed, be connected to an electromagnet to make it work. It is an electromagnet. Surf the link to our friends at Wikipedia. It's a good article, and the pics are cool.
Can a electromagnet act as a magnet when the source is dc?
yes it can
How does auto transformer work with DC supply?
Transformers don't work with DC supplies - they only work on AC.
Why dc source is used for dc supply?
it is only work on it so that used
The rotating electromagnet coil assembly in a dc motor is called what?
it is called an armature
How do motors that do NOT use magnets work?
Motors that do not have magnets work exactly the same. The permanent magnet is replaced by a electromagnet, which is a coil of wire with a voltage applied to it. This electromagnet is what produces the magnet field necessary for a motor to operate. It is just easier and lighter to use this style of DC motor in larger applications.
How does a DC electromagnet work and what are its applications?
A DC electromagnet works by passing an electric current through a coil of wire, creating a magnetic field. This magnetic field can attract or repel objects made of magnetic materials. Applications of DC electromagnets include use in electric motors, generators, relays, MRI machines, and speakers. They are also used in industrial applications such as lifting and moving heavy objects using magnetic cranes.
Is an electromagnet always magnetic?
No. Only when an electric charge is put through the electromagnet.
How do electromagnet fire alarms work?
the electromagnet makes the door close when a fire alarm goes off
Why semiconductors work on DC only?
the NP or PN junction only allows current to flow in one direction (think diode), therefor DC would be the only energy capable
Can a DCC equipped model train work on a DC track?
It can only work if you add a converter inside.
What are the devices that make used of electromagnet?
AC/DC Motors, Generators etc. are the devices that make Used of electromagnets.
