| Contd. -2- 15.2.26. P.S. On actually referring to your letter of the 2nd. inst. I find that your reason for the reduction of the thickness of the ebonite is mainly that it would reduce the internal resistance on discharge. Surely, however, if it will do this, it will also reduce the ohmic resistance on charge. Taking all things into consideration, I feel that you are right in suggesting a reversion to the .4 mm. ebonites. E.F.C. | ||
