Kirchhoff's loop rule

Parts a and b of the drawing contain a resistor and a battery.


(a) For drawing (a), proceed from point A to point B and determine the potential drops and potential rises.
Potential drops Potential rises
IR V
V IR
None IR + V
IR + V None


(b) For drawing (b), proceed from point A to point B and determine the potential drops and potential rises.
Potential drops Potential rises
None IR + V
IR + V None
IR V
V IR



(c) Using Kirchhoff's loop rule, find the value of the current I in part c of the drawing, where R = 7.4 .

Number Unit
