For both designs, the supply voltage is nominally 9 V and varies by +/- 1V. For the first design, assume that the availability of supply current is not a problem, and thus operate the diode at 20mA.
Design a 7.5-V zener regulator circuit using a 7.5-V zener specified at 12mA. The zener has an incremental resistance r(z) = 30 ohms and a knee current of 0.5mA. The regulator operates from a 10-V s
define a one-dimensional potential well having energies U as a function of position x as follows: U=infinity for x= -1nm to x=0; U=0 eV for x=0 to x=5nm; U=10 eV for x=5nm to x=7nm; U=0 for x>7nm
