here i am using bt138 triac. by following app notes i will try to calculate snubber ckts but my doubt is whether a triac(BT138) can be used to switch a capacitor (power cap) to AC MAINS(240V). in every app notes it is given that load may be inductive or resistive or a combination of R and L, but no where mentioned it as capacitive, this raises my doubt. can u pls explain me breifly
