A1.A cell is a device that converts chemical energy to electrical energy. 

A2.The electrodes, the electrolyte, and the container.

A3.The electrodes are the current conductors of the cell. The electrolyte is the solution that acts upon the electrodes. The container holds the electrolyte and provides a means of mounting the electrodes.

A4.Primary and secondary.

A5.The secondary cell can be restored to its original condition by an electric current. The primary cell cannot.

A6.The process of converting chemical energy into electrical energy.

A7.(a) the anode, (b) the cathode.

A8.The positive charge caused by electrons leaving the negative electrode attracts the negative ions.

A9.By current flow through the load.

A10.The chemical action between the negative electrode and the electrolyte. 

A11.The sulfuric acid is chemically acting upon the anode and cathode which creates a current flow through the load.

A12.The charging currents causes the lead sulfate in the anode and cathode to be changed back to lead peroxide, sponge lead, and sulfuric acid.

A13.Fully charged.

A14.Vent the cell, add a material rich in oxygen, and use a material that will absorb hydrogen.

A15.Current flow in a cell with no external load.

A16.The zinc container.

A17.The electrolyte is not a liquid but is in the form of a paste.

A18.The period that a cell can be stored and still be useable.

A19.The danger of explosion.

A20.Cost, size, ease of replacement, and voltage or current needs.

A21.Lead-acid, nickel-cadmium (NICAD), silver-zinc, and silver-cadmium.

A22.Can be charged in a shorter time, can deliver a larger amount of power, and stays idle longer.

A23.Silver-zinc cell.

A24.Silver-cadmium, silver-zinc, and nickel-cadmium.

A25.A voltage source in a single container made from one or more cells.

A26.Series, to increase voltage but not current. Parallel, to increase current but not voltage. Series-Parallel, to increase both current and voltage.

A27.The cells in the nicad battery can be replaced.

A28.By looking at the nameplate data.

A29.To measure the amount of active ingredient in the electrolyte.

A30.Electrolyte B. It is heavier per unit volume.

A31.At all times.

A32.Forty hours.

A33.No, a current must be passed through the battery.

A34.Reduce the charging rate.
