Yes. Transformers operate on the theory of inducing current in one coil by starting and stopping the current in another coil on the same iron core. The voltage changes as a function of the turns ratio of the primary (driven) side to the secondary (output) side. Alternating current changes rapidly each second (e.g., 50, 60 400 Hz). To use a transformer in DC-to-DC converters, you first need to create a wave, run it through the transformer to get the new voltage, then rectify and filter it to restore the output to a DC voltage. Is this a trick question? AC in and AC out. Straight DC won't work without help. The DC is "switched" or "chopped" or "turned on and off" quickly in the primary, and this action will allow the pulsating DC in the primary to drive the secondary of the transformer. Problem solved.
UPS (UNINTERUPTED POWER SUPPLY ) Its charg only AC current (Alternating current). and inverter provide current DC TO AC ( Direct current to Alternating current)
AC supply means the supply voltage is alternating one. Supply has some particular frequency and magnitude. e.g. usual power supply to domestic use DC supply means the supply voltage (or current) is not alternating. It is fixed one. i.e. frequency is zero. e.g. batteries
yes but the device will not work property or nor work at all <<>> No, the 100 mA adapter will be too small to operate a device that requires 300 mA for its operation. By trying to draw a higher current than the adapter can supply, the adapter will heat up and possibly burn itself open. In other words the adapter will stop working.
Of course, when we convert dc to ac, we need to feed an electronic circuit using transformers that have a range efficiency between 80 to 90, depends on the iron composition of the frame.
Because it does not allow ac to pass through it...
Transformers only work on ac supply because it principle is mutual induction. DC supply has constant magnitude whereas AC has alternating magnitude. so we can step up or step down current/voltage in transformer in ac only.
Transformers don't work with DC supplies - they only work on AC.
No transformers only work with AC.
No. Transformers only work with AC. Tongue-voltage is DC.
No. Transformers only work with AC. Tongue-voltage is DC.
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.
AC is preferred in distribution due to the economy, efficiency, and reliability of transformers.
yes its does the higher the current will blow out the transformers
Basically AC motors would not work on DC supply but there's however an exception for a Universal motor also known as a series motor. This is the only motor as far as I know that work on both AC and DC.
A stp-down transformer steps voltage down from a high value to a low value. Transformers only work with AC.
Not usually. Transformers require a varying magnetic field, which is induced by AC voltage.
The transmission of electrical energy requires very high voltages (for a given load, the higher the supply voltage, the lower the load current). To increase/reduce these voltages, you need transformers. Transformers are AC machines; they do not work with DC.
