The Hydraulic Analogues of Basic Circuits: Labs for Online Learning Environments
J. S. Bobowski
In this paper we describe a couple of exercises that we developed for our online first-year EM course. The labs that we describe are focused on basic concepts from circuit analysis…
Modeling and measuring the non-ideal characteristics of transmission lines
J. S. Bobowski
We describe a simple method to experimentally determine the frequency dependencies of the per-unit-length resistance and conductance of transmission lines. The experiment is intend…
Automation of the Cavendish Experiment to 'Weigh the Earth'
J. J. Andrews, J. S. Bobowski
We describe a simple and inexpensive method for automating the data collection in the well-known Cavendish torsion balance experiment to determine the gravitational constant . T…
Non-radiative mid-range wireless power transfer: An experiment for senior physics undergraduates
S. D. Delichte, Y. J. Lu, J. S. Bobowski
A wireless power transfer experiment suitable for senior physics undergraduates that operates between 3 and 4 MHz is described and demonstrated in detail. The apparatus consists of…
Quantitative Stirling Cycle Measurements: P-V Diagram and Refrigeration
Y. J. Lu, Hiroko Nakahara, J. S. Bobowski
This paper describes simple modifications to a demonstration Stirling engine that allows one to make quantitative measurements of the Stirling cycle. First, we describe measurement…
Using split-ring resonators to measure the electromagnetic properties of materials: An experiment for senior physics undergraduates
J. S. Bobowski
A spilt-ring resonator experiment suitable for senior physics undergraduates is described and demonstrated in detail. The apparatus consists of a conducting hollow cylinder with a…
