INTRODUCTION A rectifier converts AC voltage from the power transformer into the DC voltage required by an electronic device. Several devices can perform this conversion, including silicon diode chains (solidstate technology) and various tubes. The differences between the types are how much AC is converted to DC and the speed at which the conversion occurs. As part of this conversion, in a tube rectifier, electrons travel from the inner tube (cathode) to the outer tube (anode) Because of this travel time, tube rectifiers exhibit what is called "sag." While electrons move very quickly, the conversion is not instantaneous; the rectifier requires a few milliseconds for the conversion. The approximate travel time is given biy 2* M --*R1 * z * time = 1+-+-+- 3 10 42 216 where Q = charge of the electron (1.60206E-19 coulombs) M-mass of the electron (9.1083E-31 kg) V-accelerating voltage in volts R1 radius of the inner tube (cathode R2 = radius of the outer tube (anode) Z = ln(R2R1); that is, natural log of R2R1 ASSIGNMENT Write a C program that asks the user to enter the accelerating voltage in volts, the radius of the inner tube, and the radius of the outer tube. Compute the values for Z and time. Print the values of voltage, inner radius, outer radius, and time to the screen
