Statement : Any linear bilateral network containing one or more generators can be replaced by an equivalent circuit consisting of current source (INOR) in parallel with admittance (YNOR). The INOR is the short circuited current flowing through the output terminal and YNOR is the admittance measured across the output terminal with all the sources replaced by its internal impedance.
Aim : To verify Norton's theorem.

To Find Norton's Resistance
1. Connect the circuit as per the circuit
diagram {Figure (c)}.
2. Replace the supply by its internal resistance
and open circuit the load.
3. Using multimeter in resistance mode, measure
the resistance across the outout terminal (RTH).
Norton' Circuit
1. Connect the current source (INOR) and
admittance (YNOR) in parallel as shown in Figure (d).
2. Connect the load resistance (1kΩ).
3. Switch on the current source and measure the
voltage drop across load resistance using voltmeter.
4. Voltage measured at figure (a) should be equal to the voltage measured at Figure (d).
