Question 471Electricity & Electronics - QMED
70% to passWhen a low input voltage is delivered to a transformer which then produces a high output voltage, what is the proper name for the transformer type?
Astep-up transformer
Bprimary transformer
Cstep-down transformer
Dsecondary transformer
AI Explanation
The correct answer is A) step-up transformer. In a step-up transformer, the low input voltage is transformed into a higher output voltage. This is achieved by having more turns in the secondary winding of the transformer compared to the primary winding. The increase in the number of turns causes the voltage to step up from the input to the output. The other options are incorrect because: B) primary transformer is not a standard term for this type of transformer. C) a step-down transformer would decrease the voltage from input to output. D) secondary transformer is not a standard term for this type of transformer.
