Kirchoff's law -two approaches

KIRCHOFF’S LAW : KIRCHOFF’S LAW RULES AND NUMERICALS

TWO APPROACHES TO LOOP RULE : TWO APPROACHES TO LOOP RULE Select a direction of traversing the loop If the source of e.m.f sends current in the direction of traversing then it is taken as positive If the direction of current in a resistor is along the direction of traversing then it is taken as positive The equation is ?E=?IR Select a direction of traversing the loop E.m.f is negative if we go from positive terminal to negative i.e higher to lower potential Current is negative if we from higher to lower potential i.e along the direction of current flowing Equation is ?(E-IR) =0
