Question

question 9
which power source is considered to be the most versatile?
conventional
engine driven
conventional rectifier
inverter
question 10
what determines the duty cycle for any given power source?
the electrode in use
the outlet youre plugged into
the polarity in use
the machines rated output

Explanation:

For Question 9, inverters are highly versatile as they can convert DC to AC and vice - versa, adjust voltage and frequency, and are used in a wide range of applications. For Question 10, the machine's rated output determines how long it can operate continuously within its design limits, which defines the duty cycle.

Answer:

Question 9: D. inverter
Question 10: D. the machine's rated output
