What is the equivalent voltage source in Thevenin's theorem?
Step 1: Understand that Thevenin's theorem helps simplify complex circuits.
Step 2: Identify the part of the circuit you want to analyze.
Step 3: Remove the load resistor (if there is one) from the circuit.
Step 4: Calculate the open-circuit voltage (Voc) across the terminals where the load was connected. This is your equivalent voltage source.
Step 5: Find the equivalent resistance (Rth) of the circuit by turning off all independent sources (replace voltage sources with short circuits and current sources with open circuits) and calculating the resistance seen from the terminals.
Step 6: Now you have an equivalent circuit with a single voltage source (Voc) in series with a resistance (Rth).
