Anode and cathode are electrodes used in electrochemical cells to facilitate the flow of electrons.

• Anode is the electrode where oxidation occurs and electrons are lost.

• Cathode is the electrode where reduction occurs and electrons are gained.

• In a battery, the anode is the negative terminal and the cathode is the positive terminal.

• In an electrolytic cell, the anode is the positive terminal and the cathode is the negative

Valves are devices used to control the flow of fluids or gases in a system.

• Gate valve: used to start or stop the flow of fluid by lifting or lowering a gate

• Ball valve: uses a rotating ball with a hole to control the flow

• Check valve: allows flow in one direction and prevents backflow

• Globe valve: controls flow by raising or lowering a disc against the flow

• Butterfly valve: uses a disc to control flow by rotating it

QAP, WPS, and DFT are important documents used in inspection engineering.
