Question: In a series circuit with two resistors R1 and R2, what is the total resistance (R_total)?

Options:

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

Correct Answer: R_total = R1 + R2

Solution: 

In a series circuit, the total resistance is simply the sum of the individual resistances: R_total = R1 + R2.

Questions & Step-by-Step Solutions

In a series circuit with two resistors R1 and R2, what is the total resistance (R_total)?
  • Step 1: Identify the two resistors in the series circuit, which are R1 and R2.
  • Step 2: Write down the formula for total resistance in a series circuit, which is R_total = R1 + R2.
  • Step 3: Measure or note the values of R1 and R2.
  • Step 4: Add the values of R1 and R2 together to find R_total.
  • Series Circuit Resistance – In a series circuit, the total resistance is the sum of the individual resistances, which is a fundamental principle in electrical circuits.
