The prognosis for autoimmune skin disease depends on your dog's specific diagnosis and the severity of symptoms. This is a potentially life-threatening condition... In general, this is a potentially life-threatening condition requiring extensive diagnostic tests and treatments.
As an example, take the case of a highly inductive load and an angle Î¸ = 60Â°. The triac is turned on atpoint A (60Â°). It will conduct during an angle Î± greater than 180Â°, in the neighborhood of 250Â°. It is blocked at point B:(290Â°).
The SCR equivalent circuit of the triac is shown in Fig. 21.4. Fig. 21.3 Suppose the main terminal MT 2 is positive and main terminal MT 1 is negative. If the triac is now fired into conduction by propergate current, the triac will conduct current following the path (lefthalf) shown in Fig. 21.3 (ii). In relation to Fig. 21.4, the SCR 1 is ON and the SCR 2 is OFF. Now suppose that MT 2 is negative and MT 1 is positive.
