Q.
See the electrical circuit shown in this figure. Which of the following equations is a $correct$ equation for it
A) $\varepsilon_{1} - \left( i_{1} + i_{2} \right)R - i_{1}r_{1} = 0$
B) $\varepsilon_{2} - i_{2}r_{2} - \varepsilon_{1} - i_{1}r_{1} = 0$
C) $- \varepsilon_{2} - \left( i_{1} + i_{2} \right)R + i_{2}r_{2} = 0$
D) $\varepsilon_{1} - \left( i_{1} + i_{2} \right)R + i_{1}r_{1} = 0$
Explanation
(a) According to kirchhoff’s voltage law only option (a) is correct
