Questions & Step-by-Step Solutions

What is the total resistance of a circuit with a 3Ω and a 5Ω resistor in series?
  • Step 1: Identify the resistors in the circuit. We have a 3Ω resistor and a 5Ω resistor.
  • Step 2: Understand that when resistors are in series, you add their resistances together.
  • Step 3: Write down the formula for total resistance in series: Total resistance R = R1 + R2.
  • Step 4: Substitute the values of the resistors into the formula: R = 3Ω + 5Ω.
  • Step 5: Perform the addition: 3Ω + 5Ω = 8Ω.
  • Step 6: Conclude that the total resistance of the circuit is 8Ω.
