when a steelcored reactor and a non rective resistor


 are connected in series to a 150v a.c.,supply a


 current of 3.75A flows in the circuit. the p.d


across the rector and resistor are found to be


120V and 60V respictively. If the d.c resistance


of the reactor are found to be 4.5ohm,determine


the core loss in the reactor and calculate 


its equivalent series resistance


 


ANS: 77.5W,5.5ohms.


plz solve this


thank you

A voltmeter has a resistance G and range V. Calculate the resistance to be used to extend its range to nV.
 
 
To extend the range of a voltmeter we add a resistance of more value in series with the meter. value of added resistance(shunt) R s =R m +V'/I m Here V' is the new range, R m is resistance...

The speed of the yellow light a certain liquid is 2.4*10^8ms^-1.Find the refractive index of the liquid.
 
 
the refractive index is such that the (actual velocity )/(found velocit) thus rf=1.25 aproove by clicking yes below
