Three resistors connected in series have individual voltages labeled $\rm{V_{1}}$, $\rm{V_{2}}$ and \rm{V_{3}} respectively. Which of the following expresses the value of the total voltage $\rm{V_{T}}$ taken over the three resistors together?
Difficulty: Easy
A:
$\rm{V_{T}=V_{1}+V_{2}+V_{3}}$
B:
$\rm{V_{T}=\frac{1}{V_{1}}+\frac{1}{V_{2}}+\frac{1}{V_{3}}}$
C:
$\rm{V_{T}= \left( \frac{1}{V_{1}}+\frac{1}{V_{2}}+\frac{1}{V_{3}} \right)^{-1}}$
D:
$\rm{V_{T}=V_{1}=V_{2}=V_{3}}$
