A transformer changes ac to dc.
A transformer responds only to dc.
A center tap (CT) is a connection at the midpoint of the secondary winding of a transformer.
The primary is the winding connected to the source, and the secondary is the winding connected to the load.
An autotransformer is one in which the primary and secondary are automatically coupled.
A transformer consists of two or more cores that are electrically coupled on a common core.
In a certain transformer, the input power to the primary isW. If 8.5 W are lost to the winding resistance, what is the output power to the load, neglecting any other issues?
How many primary volts must be applied to a transformer with a turns ratio of 0.1 to obtain a secondary voltage of 9 V?
The primary winding of a transformer hasV ac across it. What is the secondary voltage if the turns ratio is 8?
A transformer

To stepV ac up toV ac, the turns ratio must be
What is the coefficient of coupling for a transformer in whichof the total flux generated in the primary does not pass through the secondary?
A certain transformer has a turns ratio of 1 and a 0.coefficient of coupling. When 2 V ac is applied to the primary, the secondary voltage is
When a load resistor is connected across the secondary winding of a transformer with a turns ratio ofthe source "sees" a reflective load of
What kVA rating is required for a transformer that must handle a maximum load current of 8 A with a secondary voltage of 2 kV?
