Why do transformers work only work on an AC supply?
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.
Is schrage motor ac?
As the motor is a three phase machine,it must be AC supply
Why can't we use DC supply in home?
in our home most of the electrical appliances can work only on ac supply e.g. tubelights, fan, refrigeratorsand so on.else we can also say that dc supply is costlier then ac for the same amount of power.
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.
Why does Jim use dc supply in oscillator circuits?
Jim use dc supply in oscillator circuits to and ac out put.
What is my 240 v supply at home ac or dc?
The household supply in the UK is 240 V and is AC (alternate current).
Can an amplifier can be operated on ac supply?
Yes, an amplifier can be operated on ac supply.
Why ac current attract?
As we touch an ac supply in which due to body resistance , we create a phase difference between the ac supply and us . As ac reverses polarity , so do we , but our polarity change is opposite to that of the polarity change of ac supply , hence our body gets attracted to the ac supply .
What is the bahaviorS of the INDUCTOR in ac supply?
Because of Ac supply, current lags voltage by 90 in Inductor.
What kind of supply is given to the circuit?
ac supply is given and then in the circuit rectifier converts ac to dc
What is the ac power supply in Thailand?
Is it 220 ac or 240 ac in Thailand
How a transformer is very useful in ac supply?
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
What is the meaning of 230V ac and 50Hz ac supply?
It is an AC supply with an rms voltage of 230 v and a frequency of 50 Hz, as used throughout Europe.
What is the use of regulator?
ac supply converted with dc supply
What is the use of a regulator?
ac supply converted with dc supply
Why the power cord be called in different place?
in north america it calls power supply cord,in europe it calls ac power cord
What is the advantages of the universal motors?
the universel motor can runs at both ac and dc supply.
