Question

1. a welder that gets its energy directly from a utility power plant si *

a.) an alternator
b.) a generator
c.) a rectifier
d.) a transformer

Explanation:

• An alternator is a device that converts mechanical energy to electrical energy in the form of alternating current.
• A generator is a device that converts mechanical energy into electrical energy. However, when a welder gets energy directly from a utility power plant, it doesn't generate its own electricity but rather uses the power from the grid.
• A rectifier is a device that converts alternating current (AC) to direct current (DC).
• A transformer is a device that transfers electrical energy from one circuit to another through electromagnetic induction. It can step - up or step - down the voltage. Welders often use transformers to get the appropriate voltage for welding from the utility power plant's supply.

Answer:

D. a transformer
