Transformer Phasing: The Dot Notation and Dot Convention...

The Dot Notation Generally, when we study about Transformers, we assume that the primary and secondary voltage and currents are in phase. But, such is not always the case. In Transformer, The phase relation between primary and secondary currents and voltages depends...

Why do we use a diac for triggering a triac ???

Why do we use a diac for triggering a triac?                It is possible to give a gate pulse on triac directly by using something that produces gate pulses. A DIAC is just such a device and...
