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
