Use \( \mathrm{KVL} \) to determine the voltages \( v_{1}, v_{2} \), and \( v_{3} \) in the given figure. Assume that \( v_{a}=6.8 \mathrm{~V}, v_{b}=5.20 \mathrm{~V} \), and \( v_{C}=7.00 \mathrm{~V} \). The voltage \( v_{1} \) is \( V \), the voltage \( v_{2} \) is \( \mathrm{V} \), and the voltage \( v_{3} \) is V.
