question 62

Multiple Choice

Three resistors connected in series have individual voltages labeled ΔV₁,ΔV₂ and ΔV₃,respectively.Which of the following expresses the value of the total voltage ΔV_T taken over the three resistors together?

• A)ΔV_T = ΔV₁ + ΔV₂ + ΔV₃
• B)ΔV_T = (1/ΔV₁ + 1/ΔV₂ + 1/ΔV₃)
• C)ΔV_T = ΔV₁ = ΔV₂ = ΔV₃
• D)ΔV_T = (1/ΔV₁ + 1/ΔV₂ + 1/ΔV₃)−¹
