Three resistors with values of R₁,R₂ and R₃,respectively,are connected in series.Which of the following expresses the total resistance,R_T,of the three resistors? A)R_T = R₁ + R₂ + R₃ B)R_T = (1/R₁ + 1/R₂ + 1/R₃) C)RT = R₁ = R₂ = R₃ D)R_T = (1/R₁ + 1/R₂ + 1/R₃)−¹

Question

Quizplus · Accepted Answer

When resistors are connected in series, the total resistance is the sum of individual resistances. Therefore, the expression for the total resistance of the three resistors connected in series is R_T = R₁ + R₂ + R₃. Option A correctly expresses this equation. Option B is incorrect as it uses the formula for resistors in parallel, whereas the question specifically mentions a series connection. Option C is incorrect as it implies that all three resistors have the same value, which is not mentioned in the question. Option D is incorrect as it includes an additional term (¹) for which there is no explanation or justification in the question.
