(i) Plot the current density vs. overvoltage (j vs. h)
relationship – the Butler-Volmer equation – for
this reaction in the range h = -0.5 to 0.5 V. Assume a transfer
coefficient a = 0.5 and vary the
exchange current density: j0 = 10-3, 10-6, 10-9 A/cm2. Define the
sign conventions for current and
overvoltage.
(ii) Plot the j vs. h relationship for j0 = 10-6 A/cm2 and a =
0.25, 0.5 and 0.75.
(iii) Plot log½j½ vs. h curves under the same approximation for j0
= 10-6 A/cm2, a = 0.5, and compare
with the corresponding Tafel approximation.
(i) Plot the current density vs. overvoltage (j vs. h) relationship – the Butler-Volmer equation –...
Describe the relationship between Butler-Volmer equation and Tafel plot(log plot).
Yes, this is one problem. Please solve ALL PARTS. Guaranteed thumbs up for the person who solves it. 3 1. Photodiode amplifier circuit You are designinga CF photosensor circuit for a light detection and ranging LiDAR) system in autonomous vehicles. The circuit utilizes a transimpedance amplifier to convert low-level RF photodiode current signal to a usable voltage output. It consists of a photodiode, an amplifier, and feedback capacitor/resistor pair as shown in Figure 1. We will derive simple equations to...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
