Accepted Answer

1.Electroplating is the process of applying a metal coating on another piece of metal (or another conductive surface) through an electro-deposition process.
2. Electrolysis is defined as a process of decomposing ionic compounds into their elements by passing a direct electric current through the compound in a fluid form.
3. Electrons are subatomic particles that revolve around an atom and in metals the movement of electrons cause the flow of current.
4. An anode is an electrode through which the conventional current enters into a polarised electrical device.

5. A voltameter is a scientific instrument used for measuring quantity of electricity (electric charge) through electrolytic action.
6. The cathode is the electrode where electricity is given out or flows out of. The anode is usually the positive side and the cathode the negative side.
7. Electrodes are conductors that are used to make contact with non metallic part of a circuit
8. LED is a light-emitting diode (a semiconductor diode which glows when a voltage is applied).
