Kirchhoff's Second Law MCQ - Practice Questions with Answers

Kirchoff's second law

The algebraic sum of all the potential across a closed loop is zero. This law is also known as Kirchhoff's Voltage law 

• Change in Potential in traversing a resistance is -iR

• Change in Potential in the opposite direction IS iR

• Traversing an e.m.f source from negative to positive terminal is -E

• 

• While in the opposite direction is E

• 

• Change in Potential in traversing a capacitor from negative to positive $\frac{q}{C}$

• While in the opposite direction is -$\frac{q}{C}$

 In closed-loop

$-i_1{R}_1+i_2{R}_2-E_1-i_3{R}_3+E_2+E_3-i_4{R}_4=0$
