Three resistors connected in series each carry currents labeled I₁,I₂ and I₃.Which of the following expresses the value of the total current I_T in the system made up of the three resistors in series? A)I_T = I₁ + I₂ + I₃ B)I_T = (1/I₁ + 1/I₂ + 1/I₃) C)I_T = I₁ = I₂ = I₃ D)I_T = (1/I₁ + 1/I₂ + 1/I₃)−¹

In a series circuit, the current flowing through each resistor is the same. Therefore, the total current $I_{T}$ is equal to the current through each resistor ($I_{1} = I_{2} = I_{3}$).
