Document Summary

Es1: electric circuits with ohmic and non-ohmic conductors. R r ( ) 124. 3 0. 4 198 1. The calculated values for r and the values for r measured by the ddm do not agree precisely. Tabulation of data. s t l o v. Known s = v / i = r. R = (cid:4672)(cid:4673)2(cid:4666) (cid:4667)2= (cid:4666)(cid:883)(cid:4667)2(cid:4666) (cid:4667)2= = 1 . Report s s = 150 1 . Determine r for v = 0. 6v, 0. 65v, and 0. 7v. Note: i is measured in ma have to change it into a. The diode is not an ohmic conductor since the plot does not display a linear relationship between the voltage and the current. R = v/i = 4. 697v/0. 003a = 1565. 7 . Report r series: r r = 1570 50 . Rs = ra + rb + rc + rd = (147. 8 + 220. 7 + 391 + 985. 1) = 1744. 6 . R r = 1570 50 .
