← A dip needle is free to turn in a vertical plane. When that plane is turned to one direction, the needle shows a dip of 30°. When the plane is turned through 90° to the perpendicular direction, the needle shows a dip of 45°. The true angle of dip at the place is closest toA series LCR circuit is connected to a 220 V AC supply whose frequency is equal to the resonant frequency of the circuit. The current is then 2 A, and at this frequency the reactance of the inductor is 300 Ω. The rms voltage across the inductor is →
