When a 210-v emf device is placed across two resistors in, Ask an Expert

Academics

When a 21.0-V emf device is placed across two resistors in series, a current of 12.0 A is flowing in each of the resistors. When the same emf device is placed across the same two resistors in parallel, the current through the emf device is 56.0 A. What is the magnitude of the larger of the two resistances?
