| C.A.P. Please note and return. RC.{R. Childs} To Rm{William Robotham - Chief Engineer}/RC.{R. Childs} 6092. BY/RD.2/B.20.1.39. VOLTAGE REGULATORS. The resistance of the field windings relative to the voltage regulator, has in the past, with the C.A.V. Regulator, been as near 6.5 ohms as possible. Will you please let us know if with the LR.{Mr Ellor}7 Regulator, the same applies, and whether the regulator is materially affected by any change in resistance of the field circuit. BY/RD. | ||
