 In regards to the second law of thermodynamics, i know that more energy must 
go into a system than what exits it.  Lets say that i have an 120 volt 
battery, powering a 110 volt electric motor.   Would i have to put twice as 
much energy back into the battery? What i mean is would i have to put 240 
volts back into the battery for the system to remain constant, or just any 
voltage greater than 120 volts?  I'm just confused.Please let me know. Thanks, 
Shawn!!
