The document discusses four lab experiments: 1) A star-delta motor starter that uses a star configuration initially for starting and then switches to a delta configuration. 2) A forward-reverse motor circuit that can change the motor's direction of rotation. 3) A PLC analog practice experiment. 4) Connecting a local area network system using various cabling standards like coaxial, UTP cable, and establishing connections between network cards and switches.
