Two coils are connected in series. With 2 A d.c. through the circuit, the p.ds. across the coils are 20 and 30 V respectively. ?
With 2 A a.c. at 40 Hz, the p.ds. across the coils are 140 and 100 V respectively. If the two coils in series are connected to a 230-V, 50-Hz supply, calculate (a) the current (b) the power (c) the power factor

If they are in series with 2A dc and the voltage drops are 20 and 30Vdc then the coil resistances are, E=I*R.
20v=10Ω , 30v=15Ω.
What does "p.ds" across the coil mean"?
