In a transformer ,when voltage decreases current increases.
but this is a violation of oms law.why?
Answer Posted / meenakshi
ppl,Ohm's law is applicable only 4 those circuits which are
CONTAINING PURELY RESISTIVE ELEMENTS (NO INDUCTANCES OR
CAPACITANCES) for all forms of driving voltage or current,
regardless of whether the driving voltage or current is
constant (DC) or time-varying such as AC. At any instant of
time Ohm's law is valid for such circuits ONLY.

How can maintain our H.T. motors used in cement plant. please send me procedure.
kVA rating of ordinary transformer is increased when connected as an auto transformer because A transformation ratio increased B secondary voltage increased C energy is transferred both inductively and conductively D secondary current increased
The ripple frequency in output of fullwave bridge rectifier is a. Half the input b. Twice the input c. Same as input

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.
