Suppose we have a closed circuit with a time-varying magnetic flux. An EMF is inducted on the circuit. Where would we put the battery representing the EMF? For example, suppose we have a resistance in the circuit and we want to know the intensity through it. Would we just set the voltage against its extremes to be equal to the EMF? If so, would we, in the general case where there are more elements, analyze each one as if there was a voltage between its extremes?
