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

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

Step 1: Identify the components in the circuit. We have a 12V battery and two resistors: one is 3Ω and the other is 6Ω.
Step 2: Understand that the resistors are in series. This means they are connected one after the other.
Step 3: Recall the formula for total resistance in a series circuit. The total resistance (Rth) is the sum of all resistances.
Step 4: Apply the formula. Add the resistance of the first resistor (3Ω) to the resistance of the second resistor (6Ω).
Step 5: Calculate the total resistance: Rth = 3Ω + 6Ω.
Step 6: Perform the addition: 3 + 6 equals 9.
Step 7: Conclude that the Thevenin equivalent resistance (Rth) seen from the terminals is 9Ω.
