Norton's Theorem:

1. Remove all sources from the circuit and determine the open-circuit voltage across the terminals where the load will be connected.

2. Calculate the short-circuit current that would flow between the terminals.

3. Represent the circuit with a current source (Norton current) in parallel with a resistor (Norton resistance) equal to the load resistance.

4. Connect the load to the terminals and calculate the current flowing through it using Ohm's Law.

Thevenin's Theorem:

1. Remove the load from the circuit and determine the open-circuit voltage across the terminals where the load will be connected.

2. Calculate the short-circuit current that would flow between the terminals.

3. Represent the circuit with a voltage source (Thevenin voltage) in series with a resistor (Thevenin resistance) equal to the load resistance.

4. Connect the load to the terminals and calculate the current flowing through it using Ohm's Law.
