chapter 6.2 Flashcards
1
Q
what is a transformer step up?
A
Raise the voltage
The number of turns of the primary coil is less than the number of turns of the secondary coil
The input voltage is less than the output voltage
2
Q
transformer step down?
A
lower the voltage
The number of turns of the primary coil is much more than the number of turns of the secondary coil
The input voltage is much more than the output voltage
3
Q
definition of transformer
A
A transformer is used to change the voltage of an alternating current
4
Q
formula?
A
primary number of turns / secondary number of turns = primary voltage / secondary voltage
5
Q
