3 what is the relation between gate current and anode current of thyristor in conduction period?

In the conduction period of a thyristor, the gate current is used to trigger the device into conduction, but once the thyristor is latched on, it remains conducting primarily due to the anode current. The gate current effectively initiates the conduction process by allowing a small amount of charge to flow, but the anode current, which is typically much larger, sustains the conduction. After the thyristor is turned on, the gate current can be removed, and the anode current continues to flow until the device is turned off by reducing the current below a certain holding value.
