Question 471Electricity & Electronics - QMED

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.
