Questions & Step-by-Step Solutions

What is the equivalent resistance of two resistors, 6 ohms and 3 ohms, connected in series?
Correct Answer: 9Ω
  • Step 1: Identify the resistors. We have two resistors: one is 6 ohms (R1) and the other is 3 ohms (R2).
  • Step 2: Understand that when resistors are connected in series, you add their resistances together.
  • Step 3: Write the formula for equivalent resistance in series: R_eq = R1 + R2.
  • Step 4: Substitute the values of the resistors into the formula: R_eq = 6Ω + 3Ω.
  • Step 5: Perform the addition: 6 + 3 = 9.
  • Step 6: State the equivalent resistance: The equivalent resistance is 9 ohms.
