Option: 1

E_1+IR_1+IR_2-E_2+E_3+E_4-IR_3-IR_4=0


Option: 2

E_1+E_4+E_3-IR_1-IR_3-IR_2-IR_4+E_2=0


Option: 3

E_1-E_4-E_3+IR_1-IR_3-IR_2+IR_4+E_2=0


Option: 4

E_1+E_4-E_3-IR_4-IR_3-IR_2-E_2-IR_1=0

As we learnt

 

Kirchoff's second law -

 

Algebraic sum of all the potential across a closed loop is zero

- wherein

This law is also known as kirchoff 's Voltage law (KVL)

 

 Potential drop is -ve

Potential gain is +ve

\Rightarrow E_1+E_4-E_3-IR_4-IR_3-IbR_2-E_2-IR_1= 0
