PLEASE DO NOT WRITE IT BY HAND
When a 23.0-V emf device is placed across two resistors in
series, a current of 14.0 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 64.0 A. What is the
magnitude of the larger of the two resistances?
When a 26.0-V emf device is placed across two resistors in
series, a current of 11.0 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 59.0 A. What is the
magnitude of the larger of the two resistances?
