Norton's theorem is an extension of researcher Hans Ferdinand Mayer ( 1895 - 1980 ) and Bell Labs engineer Edward Lawry Norton ( 1898 - 1983 ). Mayer was the only one of the two who actually published on this topic, but Norton made known his finding through an internal technical report at Bell Labs. containing only voltage sources, current sources, and resistors can be converted to a Norton equivalent circuit.]] CALCULATION OF A NORTON EQUIVALENT CIRCUIT To calculate the equivalent circuit: # Calculate the output current, ''I''AB, when a Short Circuit is the Load (meaning 0 resistance between A and B). This is INo. # Calculate the output voltage, ''V''AB, when in Open Circuit condition (no load resistor - meaning infinite resistance). RNo equals this VAB divided by INo.
Case 2 can also be thought of like this:
CONVERSION TO A THéVENIN EQUIVALENT To convert to a Thévenin equivalent circuit, one can use the following equations: : : EXAMPLE OF A NORTON EQUIVALENT CIRCUIT In the example, the total current ''I''total is given by: : |
