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

How many time constants must elapse for initially uncharged capacitor in an RC series circuit to be charged to 99% of its equilibrium charge?
 
 
Charge q across the capacitor is q = q 0 (1 − e -t/T ) Solve 0.99 = (1- e -t/T ) to find t/T = 0.46 or t = 0.46 T
