Question

While moving opposite to the direction of current through a resistor, how is the potential change treated?

Options

• Potential decreases, so the term is negative

• The term is always a negative emf

• Potential increases, so the term is positive

• Potential stays unchanged, so the term is zero

Answer 1

Moving opposite to the current through a resistor corresponds to a potential increase. The term is taken as positive in KVL.
