Answer 1

Concept:

Duty cycle:

It is defined as the ratio of arc on time to total time.

i.e. \({\bf{Duty}}\;{\bf{cycle}} = \frac{{{\bf{Arc}}\;{\bf{on}}\;{\bf{time}}}}{{{\bf{Total}}\;{\bf{time}}}}\)

Calculation:

Given:

Total time = 10 min, Dwell time = 4 min, Arc on time = 5 min, Duty cycle = ?

Now, we know that

\({\bf{Duty}}\;{\bf{cycle}} = \frac{{{\bf{Arc}}\;{\bf{on}}\;{\bf{time}}}}{{{\bf{Total}}\;{\bf{time}}}}\)

\({\bf{Duty}}\;{\bf{cycle}} = \frac{5}{{10}} = \frac{1}{2}\)

∴ % Duty cycle = 50 %
