4.38 A diode operates in a series circuit with a resistance R and a dc source V. A designer, considering using a constant-voltage model, is uncertain whether to use 0.7 V or 0.6 V for V D . For what value of V is the difference in the calculated values of current only 1%? For V = 3 V and R = 1 k , what two current estimates would result from the use of the two values of V D ? What is their percentage difference?
