MCQ
For the circuit given below, the Kirchoff's loop rule for the loop $BCDEB$ is given by the equation
  • A
    $- i _{2} R _{2}+ E _{2}+ E _{3}+ i _{3} R _{1}=0$
  • B
    $- i _{2} R _{2}+ E _{2}- E _{3}+ i _{3} R _{1}=0$
  • $i _{2} R _{2}+ E _{2}- E _{3}- i _{3} R _{1}=0$
  • D
    $i _{2} R _{2}+ E _{2}+ E _{3}+ i _{3} R _{1}=0$

Answer

Correct option: C.
$i _{2} R _{2}+ E _{2}- E _{3}- i _{3} R _{1}=0$
c
In a loop BCDEB by KVL

$v _{ a }- i _{2} R _{2}- E _{2}+ E _{3}+ i _{3} R _{1}= v _{ B }$

$i _{2} R _{2}+ E _{2}- E _{3}- i _{3} R _{1}=0$
