Three resistors connected in series have individual voltages labeled DV1, DV2, and DV3, respectively. Which of the following expresses the value of the total voltage DVT taken over the three resistors together?
a. DVT = (1/DV1 + 1/DV2 + 1/DV3) c. DVT = (1/DV1 + 1/DV2 + 1/DV3)-1 b. DVT = DV1 = DV2 = DV3 d. DVT = DV1 + DV2 + DV3
