Why frequency remains constant in transformer?
First we know that transformer is a statical electrical device that transfer electrical energy from one circuit to another circuit with out change its frequency .....it may be voltage or current is change simultaneosuly or separately .... and point is why does not change the frequency in the transformer because the there is no moving part in transformer....As we know that frequency is depends upon the rotation....
Which type of transformer is used in sonometer?
A sonometer is used to determine the frequency of alternating current. A step down transformer is used for the determination of frequency of A.C. because the voltage of the A.C. mains is 220V, which is dangerous. The step down transformer reduces this voltage to 6 volts.
What does transformer coupled mean?
It means a signal has no direct (galvanic) connection to the next circuit, rather, the signal is sent (coupled) only through the magnetic field in the transformer. This is used where unwanted DC current would flow, or where a ground loop would result if a direct connection was used.
Eddy current in transformer?
Yes, a transformer has eddy currents.
What is the function of the primary current when the secondary winding of the transformer is open?
When the secondary of a transformer is opened, there is no longer any load on the transformer. There will be some current flowing in the primary winding, which is needed to induce the voltage in the secondary. This primary current is referred to as the "no load" current, and is indicative of the core losses in the transformer.
What type of transformer connection can be used when it is necessary to rectify alternating current into direct current with a minimum of ripple?
bride transformer
What happens when frequency is increased of transformer?
When the frequency of a transformer is increased, the core losses of the transformer increase due to increased eddy current losses and hysteresis losses. This results in a rise in temperature of the transformer. Additionally, higher frequency can affect the impedance of the transformer and alter the voltage regulation and efficiency.
What will happen to frequency of current when voltage is changed using a step up or step down transformer?
Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.
Is transformer work without freqency?
No. A transformer has to have AC, alternating current, to work. And since it's alternating, it'll have a frequency.
Does a transformer changes the frequency of incoming supply?
Yes the transformer effects the incoming frequency supply. This frequency is dependent on the core lamination of the transformer the weightier the core lamination the lesser will be the frequency we get and vice verse..

What formula would be used to convert at current transformer rating at 60Hz to 25Hz?
I don't understand your question. Are you asking how to convert from 60hz to 25hz using a transformer? That cannot be done. Frequency in = frequency out.
If the frequency is drop What will happens a step up transformer?
If the frequency drops, then overall impedence reduces and hence the current tend to increase, leading to over heating and ultimately may damage the transformer
What will happen if you pass AC current through a transformer?
If the transformer was designed for the specific frequency in use, it will step up or down voltage and current as it was designed to do. Transformers transform how power "looks" by increasing and decreasing voltage and current, while keeping power output equivalent to input (if you ignore the transformer losses).
WHAT IS the working principal of electrical transformer?
to provide required current one ckt to another without change in frequency
Which type of transformer is used in sonometer?
A sonometer is used to determine the frequency of alternating current. A step down transformer is used for the determination of frequency of A.C. because the voltage of the A.C. mains is 220V, which is dangerous. The step down transformer reduces this voltage to 6 volts.
Are intermediate frequency transformers are step up transformers?
Intermediate frequency transformers can be either step-up, step-down, or 1:1. The term "intermediate frequency" relates to the frequency of operation, and not to the voltage or current conversion ratios. An "intermediate frequency transformer" is a special purpose transformer used for filtration purposes in radio reception, rather than voltage or current conversion, though a step-up or step down turns-ratio may be used in the design.
