Direct Current Circuit Consider a wire with resistance R = ρ‘/A connected to a battery. Resistor rule : In the direction of I across a resistor with resistance R , the electric potential drops: Δ V = - IR . EMF rule : From the ( - ) terminal to the (+) terminal in an ideal source of emf, the potential rises: Δ V = E . Loop rule
