Question: If two resistors, R1 and R2, are in series, what is the equivalent resistance (R_eq)?

Options:

  1. R_eq = R1 + R2
  2. R_eq = R1 * R2
  3. R_eq = R1 / R2
  4. R_eq = R1 - R2

Correct Answer: R_eq = R1 + R2

Solution: 

The equivalent resistance of resistors in series is given by R_eq = R1 + R2.

Questions & Step-by-Step Solutions

If two resistors, R1 and R2, are in series, what is the equivalent resistance (R_eq)?
  • Step 1: Identify the two resistors you have, R1 and R2.
  • Step 2: Understand that when resistors are in series, the total resistance is the sum of their individual resistances.
  • Step 3: Write down the formula for equivalent resistance in series, which is R_eq = R1 + R2.
  • Step 4: Substitute the values of R1 and R2 into the formula.
  • Step 5: Perform the addition to find the equivalent resistance R_eq.
  • Series Resistors – In a series circuit, the total or equivalent resistance is the sum of the individual resistances.
