After one cell is assembled‚ a multimeter can be used to measure the voltage or the electrical current from the voltaic cell; a typical voltage is 0

power is the ability to get someone to do something he or she would not otherwise do” Work-Energy PrincipleThe change in the kinetic energy of an object is equal to the net work done on the object.This fact is referred to as the Work-Energy Principle and is often a very useful tool in mechanics problem solving. It is derivable from conservation of energy and the application of the relationships for work and energy‚ so it is not independent of the conservation laws. It is in fact a specific application

(from http://www.wikihow.com/Diagnose-and-Replace-a-Failed-PC-Power-Supply) Diagnosing a Failed PC Power Supply 1Make sure that everything is plugged in. It’s entirely possible that a cord could just slip out from the outlet while you’re working. If power is present to the monitor and other peripherals‚ yet there is no power to your computer‚ there is likely something wrong with your power supply. 2Hit the power button. The most obvious clue is that the system will do absolutely nothing
