Assume that the silicon diode in the given circuit requires a minimum current of 1 mA to be above the (knee-point voltage = 0.7 V) of its `I-V` characteristics. Assuming that the voltage across the diode is independent of current above the knee-point, find the maximum value of R so that the voltage is above the knee-point if `V_(B) = 5A`. Also find the value of R to establish a current of 5 mA in the circuit for the since voltage.img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/NEP_NGM_PHY_MP_C05_E01_008_Q01.png" width="80%"
