This lab helps the students to study the various types of wiring systems used onboard, familiarising with the working use of various instruments used in the electrical workshop, calibration of instruments like volt meter, ammeter etc., measurement of resistances, equivalent resistances under series, parallel and series-parallel connections, conducting continuity test using ohm meter and multi-meter, study of volt —ampere characteristics of lamps, measurement of low restance by Kelvin Double bridge, use of watt meter and measurement of power etc.
