Question
This quantity is known as the line regulation and is usually expressed in mV/V. (b) Generalize the expression above for the case of m diodes connected in series and the value of R adjusted so that the voltage across each diode is 0.7 V (and V. =0.7m V). (c) Calculate the value of line regulation for the case v* = 10 V (nominally) and (i) m =1 and (ii) m = 3. %3D
