To 19 Order No Customer's No. Z through which the current from the magneto then passed quietly instead of discharging through the air. This path conducted sufficiently to light a lamp on 200 volts though it became red-hot and smoked with the current. A similar experiment was carried out with a small piece of bakelite and exactly similar results were obtained. A piece of ebonite subjected to the same treatment merely burned away, without forming a conducting (contd) Signed This Sheet must be filed on completion of the work. | ||
