A transformer in which the secondary voltage is more than the primary voltage is called a(n) _____ transformer.

A) step-down
B) step-up
C) isolation
D) auto

Step-Up Transformer

A transformer that produces a higher voltage at its secondary than is applied to its primary.

Secondary Voltage

The voltage output by the secondary winding of a transformer or another type of electrical converter, which has been transformed from the primary voltage.

Primary Voltage

The voltage supplied to the primary winding of a transformer, which induces a secondary voltage in accordance with the transformer's winding ratio.
