• A. ratio of rotor current limits = ratio of lower limit to upper limit current
• B. ratio of rotor current limits > ratio of lower limit to upper limit current
• C. ratio of rotor current limits < ratio of lower limit to upper limit current
• D. no relation between ratio of rotor current limits and ratio of lower limit to upper limit current
