Three Resistors Connected in Series Have Individual Voltages Labeled $\Delta$ V₁ $\Delta$

question 66

Multiple Choice

Three resistors connected in series have individual voltages labeled $\Delta$ V₁, $\Delta$ V₂, and $\Delta$ V₃, respectively. Which of the following expresses the value of the total voltage $\Delta$ V_T taken over the three resistors together?

• A) "\(\Delta\)V_T = (1/\(\Delta\)V₁ + 1/\(\Delta\)V₂ + 1/\(\Delta\)V₃)"
• B) "\(\Delta\)V_T = \(\Delta\)V₁ = \(\Delta\)V₂ = \(\Delta\)V₃"
• C) "\(\Delta\)V_T = (1/\(\Delta\)V₁ + 1/\(\Delta\)V₂ + 1/\(\Delta\)V₃) ^{- 1}"
• D) "\(\Delta\)V_T = \(\Delta\)V₁ + \(\Delta\)V₂ + \(\Delta\)V₃"
