- 2 2 A For The Thyristor Circuit Shown In Fig Q2a The Scr Has A Latching Current Of 18ma And Is Fixed By A Pulse Of 1 (25.67 KiB) Viewed 47 times
2. 2 (a) For the thyristor circuit shown in Fig. Q2a, the SCR has a latching current of 18mA and is fixed by a pulse of length 50us. When R2 is removed, the SCR failed to remain 'ON' after the firing pulse ends. Investigate the cause of this failure.
