2. Norton’s Theorem
Norton's Theorem states that it is possible to simplify any linear circuit,
no matter how complex, to an equivalent circuit with just a single
current source and parallel resistance connected to a load.
4. Steps to Apply Norton's Theorem
● Step 1: Identify the load resistor
● Step 2: Remove the load resistor and open the terminals
● Step 3: Determine the short-circuit current (I_sc)
● Step 4: Determine the equivalent resistance (R_th)
● Step 5: Draw the Norton equivalent circuit
● Step 6: Reconnect the load resistor
5. Advantages and Limitations
● Norton's theorem is only applicable to linear circuits that have a
constant resistance.
● Non-linear circuits or circuits with varying resistance cannot be
simplified using Norton's theorem.
● Limited to DC circuits: Norton's theorem is limited to DC circuits,
which means it ca
