Low Voltage Effects on AC Motors A drop in voltage will result in a proportionate increase in current. If the current exceeds the nameplate rating and is not corrected‚ this can result in damage to the motor from overheating Nameplate Rating An electric motor will have a nameplate rating for both voltage and amperage. When a load is on a motor‚ the motor must draw a fixed amount of power. The required power is about equal to volts times amps. Should the voltage fall below the nameplate rating

SOLAR POWER IN TODAYS WORLD JEROME T. GARDNER COLUMBIA SOUTHERN UNIVERSITY ABSTRACT Since first discovered in the 1860s‚ the concept of storing energy from the sun to use as a source of power has been studied and pursued by many programs. Either using solar collectors or photovoltaic cells‚ the methods of using solar power are becoming more efficient and cost-effective. Solar technology is currently being used by homes and businesses‚ but is still too expensive and risky for many residents. Researchers
