Chapter 6, Problem 6.19P
Construct a curvilinear- square map of the potential field between two parallel circular cylinders, one of 4 cm radius inside another of 8 cm radius. The two axes are displaced by 2.5 cm. These dimensions are suitable for the drawing. As a check on the accuracy, compute the capacitance per meter from the sketch and from the exact expression:
Where a and b are the conductor radii and D is the axis sepatation.

You are tasked with designing an electronic system for sensing the magnitude of a
measurand (details and values to be provided on the day of the exam).
The system must alert a user to a measurand value above a threshold, measured by an
appropriate sensor, by turning on a buzzer (to make a sound). The buzzer must remain off
below this threshold. All resistors used must be from the E12 series. This work is to be
performed on TinkerCAD.
To fully answer the question, you must provide:
• Full calculations for all components you use, clearly indicated what you are
calculating.
• A screenshot of the TinkerCAD circuit with it in the buzzer off state (clearly showing
the full circuit including the sensor).
• A screenshot of the TinkerCAD circuit with it in the buzzer on state (clearly showing
the full circuit including the sensor).
•
A written explanation of how the circuit works and justification of your design
(approx. 200 words).
