Problem on NORTON's theorem

Identify the load Remove the load resistor (RL) from the circuit and identify the two terminals across which the load was connected. Find Norton Current (IN) Short-circuit the two terminals and calculate the current flowing through the short circuit. Find Norton Resistance Deactivate all independent sources: Voltage source → short circuit Current source → open circuit Then calculate the equivalent resistance seen from the two terminals. Draw the Norton equivalent circuit Replace the original network with: Current source Resistance in parallel Reconnect the load Connect the original load across the Norton equivalent circuit. Calculate load current or voltage Using current division:
