What is the difference between a step-up transformer and a step-down transformer? a. a step-up transformer increases voltage and current. a step-down transformer does the opposite. b. a step-up transformer increases current and decreases voltage. a step-down transformer does the opposite. c. a step-up transformer increases voltage and decreases current. a step-down transformer does the opposite.

(C) A step-up transformer increases voltage and decreases current. A step-down transformer does the opposite.

Explanation:

The set-up transformer increases the voltage as the number of secondary winding turn are more as compared to the primary winding in the transformer.

 The main difference between the set up and step down transformer is that the transformer voltage output is less in the step down transformer and in the set up transformer does the inversely or opposite.

Therefore, on the step up transformer the voltage of the transformer get increased and the current deceases.
