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)R_T= R₁ = R₂ = R₃ D)R_T = (1/R₁ + 1/R₂+ 1/R₃)^-1

When resistors are connected in series, their resistances add up to give the total resistance of the circuit. Therefore, the correct expression for the total resistance of the three resistors in series is R_T = R₁ + R₂ + R₃, which is choice A. Choice B represents the formula for calculating the total resistance of resistors in parallel, not in series. Choice C is not an expression for the total resistance, but rather states that all three resistors have the same resistance value. Choice D is a slightly modified version of the formula for total resistance in parallel, but with the term (^-1) added, which does not make sense in this context.
