These modules were designed/constructed based on the text:
Principles of Electronic Instrumentation, by A. James Diefenderfer.
-
Maximum Power: In an electric circuit, the power that is delivered to a circuit element can be calculated from Ohm's law and the equation for power. When introduced to Ohm's law, the battery resistance is usually neglected. Here, it is incorporated into Ohm's law, and the power delivered to the load is found.
-
Wheatstone Bridge: This module introduces students to DC circuits involving resistors arranged in a Wheatstone bridge. For a given voltage and resistor values, the current through each resistor can be solved with the use of matrix algebra.
-
Current in an RLC Series Circuit: This module introduces students to the frequency-dependent nature of RLC circuits. As the source frequency is increased, the inductive reactance increases while the capacitive reactance decreases. When the two are equal, the circuit is said to be in resonance. The current peaks at this value while the phase angle goes to zero. In this module, students probe the current and phase angle functions within regions surrounding the resonance peak.
-
Diode: This module introduces students to the highly non-linear behavior of diodes. Real data is plotted against a theoretical model with two adjustable parameters.
