(1ai.) Graph I vs V and estimate V_D. From your grsph fit a line to the data at very small currents and a second line for the data points at high currents (plot your own graph or use mine to solve it) (ii) Use these to estimate the EEFECTIVE RESISTANCE of the diode before it becomes conductive (R_off) and after (R_on) Use parallel circuit table to solve this. (Bi.) Use the knowledge of how resistors add in parallel to estimate the EFFECTIVE RESSITANCE of the diode before and after it becomes conductive from this data (C.) How do the results from parallel current divider circuit compared to series arrangment?Explanation / Answer
Off Resistance = 1/Slope of graph (Where corrent is Zero)
1/Slope of graph = (y2-y1)/(x2-x1) = (0.3-(-4))/[0.003m-(-0.002)m]=4.3/0.005=860 K Ohms
On Resistnace =(0.86-0.7)/(800m-21.5m) = 20 Ohm
