Transformers work on the principle of mutual induction. This requires a continuously-changing magnetic field to link the primary and secondary windings, which can only be produced by a changing current in the primary winding.

why do transformers use alternating current?
Transformers use alternating current (AC) for several reasons: Easier Transformation: AC voltage can be easily stepped up or down using transformers, making it ideal for power transmission and distribution. Efficient Transmission: AC reduces energy loss during transmission due to the ability to use higher voltages and lower currents. Simple Generation: AC is easily generated using rotating machinery (e.g., generators). Polyphase Capability: AC enables the use of polyphase systems, which increase power transmission efficiency and reduce wire requirements. Economical: AC transformers are less expensive and more compact than direct current (DC) transformers. AC's changing polarity allows the magnetic field in the transformer to induce voltage in the secondary coil, enabling efficient voltage transformation.
Are Malibu low voltage transformers AC or DC?
All transformers are a.c. machines.
Can you harness the 1 100th volts that comes from your tongue using transformers and a dc to ac converter?
No. Transformers only work with AC. Tongue-voltage is DC.
Why do you use more AC versus DC?
The AC systems are more readily available. All countries national grids are AC systems. With the use of transformers the voltage can be transmitted over long distances. DC systems have their place but are not comparable to the AC systems that run countries.
How can you convert 240v to 120v for ac?
Use a step down transformer 240 primary to 120 secondary. You must know what the connected load (amps) is so that you don't overload the transformer. Small transformers are rated in VA.
Is it appropriate to use dc supply in a transformer?
Not usually. Transformers require a varying magnetic field, which is induced by AC voltage.
Why doesn't a transformer convert AC into DC?
transformers increase or decrease voltage. converters have rectifiers inside, which change ac to dc Transformers are devices that operate on the change in magnetic field, That change in magnetic field only induces an AC voltage/current into the secondary winding. From there it must be rectified to obtain DC, and is very often filtered to make it usable.
Transformer are used in circuits containing both dc and ac?
No transformers only work with AC.
Does the battery method have any limitations on testing the transformers polarity?
yes its does the higher the current will blow out the transformers
What is the purpose of AC generator?
AC voltages can be raise by transformers and transported over long distances without great power losses then converted back to lower household voltages by transfomers for our use.
How do transformers work since the two coils aren't connected to each other?
The AC - and it must be AC - in the primary coil generates an alternating magnetic field around the coil; this alternating magnetic field induces a current in the secondary.
