Why Transistors are not used as switching devices?
Answer Posted / sathish.n tessolve
Hi Friends
The reason why we are not using the transistor as
switching device because there is a chance of current flow
from VCC to ground when the transistor is ON.So the
transistor take more power.But this is never happen in the
CMOS device because only one transistor is get ON at a time.

As we use capacitior bank in 3ph ckt for improvement of PF, why not we use capacitor in single phase domestric use, at our house their are many inductive equipments,like fan,mixer,tube choke,air conditioner they also draw PF... by using capacitor can they improve PF. if yes--what are advantage and how to connect a capactor in single ph,and which type of capacitor if no- what are disadvantages.
