There is quite a bit of information on the I-V characteristic of electronic devices. In this experiment, we will plot the I-V characteristic of a diode through measurement. The relationship between the current and voltage of a diode is expressed in equation 3.1, which shows the exponential dependence of current to voltage. VD VD ID = Is (CVT - 1) = Ise (eT (Q.1) prove that for a forward-biased diode, if the voltage changes by AV, the current changes by almost 107x4V times (note that no calculator is required as long as you know log10 (e) = 0.43!)
