Apply the three-step process to simplify the resistor network: find series resistors, redraw, then combine parallel resistors to obtain an equivalent resistance of 31 ohms.
A Third Example of Simplifying a Large Resistor Network with a 3 Step Process3:34
Apply the three-step process to find equivalent resistance by identifying parallel and series groups and redraw circuit; in this example, 3.6 ohms in parallel with 5 ohms yields 8.6 ohms.

Description

Day 8 of Linear Circuits. We introduce how circuits with multiple resistors can often be simplified. If resistors are in series (same current flows through them), you can simply add their values together. If resistors are in parallel (same voltage is across them), there is a slightly different equation you can use. We also will present a simple three step process you can use to simplify all sorts of combinations of resistors.

The material covers all of the lecture material from an eighth lecture in a traditional, sophomore-level linear circuits class.
