PART – A

CONVENTIONAL EXPERIMENTS

(1) Verification of Ohm’s law and Kirchhoff’s laws.

(2) Measurement of low range resistance using voltmeter-ammeter method. Verification of resistance value using

multimeter/LCR meter.

(3) Measurement of earth’s resistance by 3-electrode method.

(4) Measurement of resistance, inductance, impedance and power factor using voltmeter, ammeter and wattmeter in

single-phase AC circuits.

(5) Measurement of three-phase power of an inductive load by 2-wattmeter method, when the load is (a) star

connected and (b) delta connected. Calculation of resistance, reactance, impedance and power factor.

(6) Wiring an appropriate electric circuit, understanding the basic principle used for 2-way and 3-way control of load.

PART – B

TYPICAL OPEN-ENDED EXPERIMENTS

Open-ended experiments are a type of laboratory activity where the outcome is not predetermined and

students are given the freedom to explore, design, and conduct the experiment based on the problem

statements as per the concepts defined by the course coordinator. It encourages creativity, critical thinking, and

inquiry-based learning.

(1) Creation of short circuit to determine the time taken by a fuse of different length. Documenting the test data and

the conclusions.

(2) Trouble shooting experiments in simple DC circuits. The trouble may be due to loose connection, faulty component

leading to open circuits or short circuits. Detection of fault and the reasons for that and conclusion.

(3) Measurement of voltage between line and neutral, ground and line, ground and neutral in respect of heathy and

unhealthy 3-pin socket. Conclusions arrived for the faulty wiring. Allowable ground voltage.

(4) A 12 V battery is available. It is required to obtain 3 V from the battery to charge a mobile. Create a circuit to

obtain the required voltage. Specify all the ratings of the components used.

(5) Only three ammeters and standard resistance are available in the laboratory. Using the same measure the single

phase power consumed by an inductive load.

(6) Only three voltmeters and standard resistance are available in the laboratory. Using the same measure the single

phase power consumed by an inductive load.
