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

two ressistance Xand Y arr in left and right meter bridge the balance point is 40 cm from left of 10 resistivety each are connected series with X AND Y seprately.the balance point is 45 cm...
X = 8 and Y = 12. in first case, X/40=Y/60 In second case, (X+10)/45= (Y+10)/55 solving these two by simultaneous equations, you get the answer :) please like and approve :)

If a copper wire is stretched to make it 0.1% longer. The percentage change in its resistance is ?
I am not quite satisfied with you.. But thanks anyway.. As far as I know R= ρ(l/A) So, as length increases by 0.1% the area of cross section that wil eventually decrease since the volume is ...
