In this exercise, the AC voltage of 100Hz is applied for the same model as Exercise 2.
The steady state after a long lapsed time is calculated.
There are no changes in the other conditions.
In this exercise, the AC voltage of 100Hz is applied.
The time step which is set in the transient analysis tab should be shorter than one eighth of the AC voltage period ( 10[ms] / 8).
The difference from Exercise 2 is indicated by red letters in the table.
