During the transition time or turn-on time:
1
The forward anode voltage increases from 10% to 90% & the anode current decrease from 90% to 10% of the initial value
2
The forward anode voltage decreases from 90% to 10% & the anode current also decrease from 90 to 10% of the initial value
3
The forward anode voltage decreases from 90% to 10% & the anode current increases from 10% to 90% of the initial value
4
The forward anode voltage increases from 10% to 90% & the anode current also increase from 10% to 90% of the initial value
