AG Mechanics CDE Practice Exam

A device on AC welders that converts high voltage and low amperage from utility power lines to low voltage and high amperage is referred to as

1. Rectifier

2. Switch

3. Transformer

4. Voltage Converter

The correct answer is: Rectifier

In AC welders, the device that is responsible for converting high voltage and low amperage from utility power lines to low voltage and high amperage is called a rectifier. A rectifier is essential for converting alternating current (AC) into direct current (DC), which is commonly used for welding applications. Options B, C, and D are not the correct answers for this question. - A switch is a device used to create, maintain, or break an electric circuit. - A transformer is used to either increase or decrease the voltage of an alternating current. - A voltage converter is a device that converts the electrical input voltage into a different output voltage level. Therefore, the correct answer is option A, Rectifier, as it specifically addresses the function described in the question.
