Draw the figure of voltaic cell explain its construction. Explain flow of current in conductor through this cell. Page 87 Chapter - 4.Electricity |
| Answer» WORKING Definitions Electrical current is the movement of charged particles, either electrons or ions, through a conductor.A voltaic cell is an ELECTROCHEMICAL cell that uses a chemical reaction to produce electrical energy. The IMPORTANT parts of a voltaic cell:The anode is an electrode whereoxidation occurs.The cathode is an electrode wherereduction occurs.A salt bridge is a chamber of electrolytes necessary to complete the circuit in a voltaic cell.The oxidation and reduction reactions are separated into compartments CALLED half-cells.The external circuit is USED to conduct the flow of electrons between the electrodes of the voltaic cell and usually includes a load.The load is the part of the circuit which utilizes the flow of electrons to perform some function | |
