One of the two largest condensers was now fitted up in a case and tested on a distributor on the bench, in comparison with a condenser of .20 mf capacity. The distributor was fitted with platinum-iridium contact points, but was otherwise standard. The spark lengths obtainable in each case were identical, both at high and low speeds, and with a slate leakage across the gap used for the test. (contd) Signed This Sheet must be filed on completion of the work. | ||
