A transformer with a turns ratio of 1000:1 is
A step up transformer
The principal application of a transformer in an x-ray imaging system is to
Change voltage
what is the transformer that looks like a square donut called
Closed core
an auto transformer
Contains a single set of coils that serves as both primary and secondary coils
Which of the following accurately represents transformer law
Is/Ip = Np/Ns
which of the following statements about transformers is correct
Laminated transformer cores are more effective than unlaminated ones
The output current in a step up transformer is
Lower than the input current
transformers have iron cores to intensify the
Magnetic field
if DC is applied to the primary coil of a step up transformer, what is the result of the secondary coil
Nothing
the turns ratio is defined as
Number of secondary windings primary windings
The transformer operates
On AC but not DC
The symbol for a transformer is
The C diagram
The transformer changes
The amplitude of the voltage
When a step up transformer is in use
The secondary voltage is greater than the primary voltage
If a transformer produces a large secondary current from a small primary current
The turns ration will be less then 1
a transformer "transforms" or changes electric
Voltage
