What is the equivalent resistance of two 10Ω resistors connected in series? (2022)
Step 1: Identify the resistors. We have two resistors, each with a resistance of 10Ω.
Step 2: Understand that when resistors are connected in series, their total or equivalent resistance (R_eq) is the sum of their individual resistances.
Step 3: Write the formula for equivalent resistance in series: R_eq = R1 + R2.
Step 4: Substitute the values of the resistors into the formula: R_eq = 10Ω + 10Ω.
Step 5: Perform the addition: 10 + 10 = 20Ω.
Step 6: Conclude that the equivalent resistance of the two 10Ω resistors in series is 20Ω.
