acteristic shown in Fig. 8.28. It tends to go asymptotic at / min and Limn, (38,39). Actual data for Cu and AgCdO contacts are shown in Figs. 8.29 and 8.30. These curves show us negative volt-ampere characteristic, i.e., as the current in the arc increases, so the voltage drop across the arc decreases. The total arc voltage is given by (see Fig. 8.19)
