  2. R1 * R2 / (R1 + R2)
  3. R1 - R2
  4. 1/(1/R1 + 1/R2)

Questions & Step-by-Step Solutions

What is the formula for the equivalent resistance of two resistors R1 and R2 in series in a Wheatstone bridge?
  • Step 1: Identify the two resistors you are working with, R1 and R2.
  • Step 2: Understand that when resistors are in series, the total or equivalent resistance is found by adding their values together.
  • Step 3: Write down the formula for the equivalent resistance: R_equiv = R1 + R2.
  • Step 4: Substitute the values of R1 and R2 into the formula if you have specific numbers.
