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

power of a cell
Power of bulb P = 4.5 V Voltage in bulb = 1.5 V Current in the bulb i will be equla to 2E / 9 2E /9 = P / V E = 9P/2V E = 9*4.5/2*1.5 E = 13.5 V Regards Nirmal Singh Askiitians Faculty

Why theres a phase reversal when wave reflects from denser surface but no phase reversal when it reflects from rarer surface?
Hello Student, If a wave reflects from an optically more dense medium than the one in which it was travelling (e.g when going from air to glass) then a phase change of π is produced,...
