A simple Question from all....
If Voltage drops then its rated value what will be effect on
a Residential load? similarly if voltage rises from its
rated value then what will be effects on a load? i know if
voltage drops the equipment or device draws more current
then its rated what are other reasons ? thanks in advance
for ur time.......

Determine the MVA rating of the power transformer given that 110/66 kV,1000 Amps. Folks how can i calculate the MVA rating with this Data??Plz Help........
What is a DC series motor?
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.
