  1. An electrochemical cell can be used to generate a current without plugging into an outlet. The cell consists of two different metal pieces called electrodes. Cells and Batteries

  2. The metals are in a solution, called an electrolyte which reacts with the metal to free up some electrons. The two eletrodes are kept seperated so that the electrons can move between them throught the soultion. When a wire is connected to each end of the cell, the electrons move through the conductor to get to the other side, creating a current through the conductor..

  3. Electrons are always repelled away from the negative end of a cell and move through the circuit and into the positive end where they are attracted

  4. When you connect several cells together, it is called a battery. • Different voltages of batteries are created by connecting together different numbers of cells.

  5. There are two types of batteries: primary and secondary

  6. Electrochemical Cells

  7. List advantages and disadvantages of each

  8. Electric Circuits A controlled path of moving electrons is called a ciruit. In order for electrons to move, there must be a continuous, complete path between a positive terminal and negative terminal. This is called a complete circuit. If the path is broken at any point, then the circuit is called incomplete.

  9. There are 3 major parts that all circuits need.These are the energy source, the path and the load.Most circuits also have a switch, though that is not always necessary.
