Problem
When writing the algebraic sum of potential differences around a closed loop, the sign attached to the term IR for a resistor depends on
(a) the magnitude of the applied emf in that branch
(b) whether the resistor lies on the clockwise or anticlockwise side of the circuit diagram
(c) whether the chosen loop direction is the same as the current through that resistor
(d) the numerical value of the resistance only
