Questions
Assume that the silicon diode in the circuit requires a minimum current of 1 mA to be above the knee point (0.7 V) of I-V characteristics. Also assume that the voltage across the diode is independent of current above the knee point. If = 5V, then the maximum value of R so that the voltage is above the knee point is
