1) As long as there is a flow of chemicals into a fuel cell, the electricity flows out of the cell.
2) Voltage of every solar cell increases 2.3mV per every °C over 25°C.
3) A primary cell, like an ordinary flashlight battery, cannot be recharged .
4) If slip of an induction motor is positive then the electric machine is running as a generator.
5) To make the direction of the current constant and the speed continuous, motor commutators change the direction of the current in every turn in a two pole DCM.
6) The current flowing through the stator or rotor coils creats the conductor losses
7) Discharge current of a battery is often expressed as D-rate
8) An AC Motor generates more power comparing with a DC motor that has the same weight.
9) A rechargable battery is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent
10) Armature is the part between the pole pairs in a DC motor
