Which transformer type would most likely have a higher voltage output?

• A. Step-down transformer
• B. Step-up transformer
• C. Both types produce equal voltage
• D. Neither affects voltage

Answer: (B)

A step-up transformer is designed specifically to increase the voltage from its primary winding to its secondary winding. This transformation occurs based on the ratio of the number of turns of wire in the primary coil compared to the secondary coil. In a step-up transformer, the secondary coil has more turns than the primary coil, which results in a higher voltage output. This principle is central to the operation of devices that need to transfer electrical energy efficiently over long distances, as higher voltages can reduce the energy losses that occur due to resistance in the wires. In contrast, a step-down transformer performs the opposite function; it reduces voltage by decreasing the number of turns in the secondary winding compared to the primary winding. Therefore, a step-up transformer is the clear choice when looking for a transformer that outputs a higher voltage.
