Questions & Step-by-Step Solutions

What is the equivalent resistance of a 5 ohm and a 10 ohm resistor in series?
  • Step 1: Identify the resistances you have. In this case, you have a 5 ohm resistor and a 10 ohm 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: R_total = R1 + R2.
  • Step 4: Substitute the values into the formula: R_total = 5 ohms + 10 ohms.
  • Step 5: Calculate the total resistance: 5 ohms + 10 ohms = 15 ohms.
  • Step 6: Conclude that the equivalent resistance of the 5 ohm and 10 ohm resistors in series is 15 ohms.
