Lab 3: Constant Current Source (LM334), Thévenin’s and Norton’s Theorem, Maximum Power Transfer
Apparatus
- DC Power Supply: with 0.01A current limit.
- Digital Multimeter
- Resistors: , , , and
- LM334 Constant Current Source
- Trimpot ,
Overview
- Thevenin’s Theorem: Decompose the linear supply side to a single voltage source and a single resistor in series.
- Norton’s Theorem: Decompose the linear supply side to a single current source and a single resistor in parallel.
- Source Transformation: A voltage source with a resistor in series is interchangable with a current source with a resistor in parallel.
