In a circuit with a 12V source and two resistors (3Ω and 6Ω) in series, what is the Thevenin equivalent resistance (Rth)?

In a circuit with a 12V source and two resistors (3Ω and 6Ω) in series, what is the Thevenin equivalent resistance (Rth)?

Step 1: Identify the resistors in the circuit. We have two resistors: R1 = 3Ω and R2 = 6Ω.
Step 2: Understand that when resistors are in series, their total resistance is the sum of their individual resistances.
Step 3: Write the formula for total resistance in series: Rth = R1 + R2.
Step 4: Substitute the values of the resistors into the formula: Rth = 3Ω + 6Ω.
Step 5: Perform the addition: 3Ω + 6Ω = 9Ω.
Step 6: Conclude that the Thevenin equivalent resistance (Rth) is 9Ω.
