Fan regulators with diac, triac and RC time constant network are more common in use. A small leakage current, called the forward leakage current, flows as shown by OM in the V-I characteristics of SCR in this mode.As the forward leakage current is small, SCR offers high impedance. CONCLUSION timing network can also be used instead of triacs, although choice of particular arrangement depends on the availability of the reliable semiconductor devices and their price. UJT will turn ON when its Vp value is reached through voltage charging across C1. NO. Single section of RC phase shifting control may cause a hysteresis phenomenon. In this lab, we also experienced building circuits for inverting, non-inverting and summing amplifiers and got basic understanding by analyzing their output signals with the help of oscilloscope and multimeter.
