Question:

Which of the following is correct according to Kirchhoff's loop rule in the following figure?

Options:

Ldi/dt + iR - q/C =  E

Ldi/dt + iR - qC =  E

Ldi/dt + iR + q/C =  E

Ldi/dt + iR + qC =  E

Correct Answer:

Ldi/dt + iR + q/C =  E

Explanation:

Kirchhoff's loop rule states that the sum of all the electric potential differences around a loop is zero. 

Ldi/dt + iR + q/C -  E = 0

Ldi/dt + iR + q/C =  E
