3-70 A-37. A-38. 0 volts. (The two inputs to the operational amplifier are both at the same potential.) A-39. An audio (or low) frequency power amplifier. A-40. A change in inductance in a series LR circuit causes a change in true power. A-41. It decreases. A-42. (a) Inductance increases; (b) true power decreases. A-43. Permeability decreases. A-44. A change in inductance. A-45. A-46. The knee of the curve. A-47. Use two load windings whose flux effects cancel in the core of the reactor or use two load windings on two toroidal cores so that load flux always aids control flux in one core and opposes control flux in the other core. A-48. The rectifier eliminates hysteresis loss. A-49. A bias winding and associated circuitry. A-50. Servosystems, temperature recorders, or power supplies.
