1. A battery , which is actually an electric cell, is a device that produces electricity from a chemical reaction.

2. Photo- electric cell (Photo cell ): A light-sensitive device which converts light signals into electrical signals.

3. Bipolar-pulse conductance measurement technique can overcome the effect of double layer polarization capacitance in electric cell and detect the conductance of solution accurately.

4. When the ends of a copper wire are joined to a device called an electric cell a steady stream of electricity flows through the wire.

5. This paper solves the analytical solution for a simple three-directional electric cell models and some good results are obtained.
