For the crews of the International Space Station (ISS), it's a reality. In 1984, President Ronald Reagan proposed a permanently inhabited, government-and industry-supported space station be built by the United States in cooperation with several other countries.
Low voltage at an outlet, or excessive voltage drop, can cause a number of fault conditions in the home wiring system. An appliance or piece of equipment can suffer erratic operation, non-operation or permanent interior damage to the circuit of the appliance with low voltage. Low voltage can cause an efficiency drop, leading to wasted energy. Low voltage can be the sign of high resistance in the circuit, branch wiring, or at the switch or outlet location. High amperage and resistance and defective or poor insulation can cause fires. Any home owner can repair low voltage at an outlet by using precaution and some basic tools and steps.
A high load current lowers the battery voltage, and the end-of-discharge voltage threshold should be set lower accordingly. Internal cell resistance, wiring, protection circuits and contacts all add up to overall internal resistance. The cut-off voltage should also be lowered when discharging at very cold temperatures.
