List of Experiments

Exp.	Theory Unit	Title	Objective / Description
1	Unit V	Electrical Safety Practices in the Laboratory	Demonstrate safe handling of electrical equipment, proper use of insulated tools, earthing, and emergency shutdown procedures. Application: Safe operation of electrical systems in laboratories and workplace
2	Unit I	Verification of Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL)	Verify Kirchhoff's Voltage Law in a series circuit and Kirchhoff's Current Law in a parallel circuit.
3	Unit I	Thevenin's Theorem Verification	Find the open-circuit voltage (Vth) and equivalent resistance (Rth) of a DC network; connect different loads and verify that measured terminal voltages match Thevenin's prediction.
4	Unit II	AC Measurements – Voltage, Current, and Frequency	Use a voltmeter and ammeter to measure single-phase AC supply voltage and load current; verify using voltmeter, ammeter and wattmeter; observe waveform and measure frequency using a basic CRO.
5	Unit II	Determination of the parameters of ac single phase series RLC circuit.	Measure the source voltage (V), circuit current (I), active power (P), and voltages across each component. Use these values to calculate impedance, individual reactances, and phase angles
6	Unit II	Resonance in an RLC series circuit	Study the phenomenon of resonance in an RLC series circuit and obtain the resonant frequency.
7	Unit II	Power and Power Factor Measurement and Power Factor Improvement Using Capacitor	Connect a single-phase inductive load (choke coil); measure voltage, current, and active power using a wattmeter; compute power factor. Add capacitors in parallel steps across the inductive load; measure and record power factor at each step; observe reduction in line current.
8	Unit III	Three-Phase Star Connection – Voltage and Current Verification	Set up a balanced three-phase star-connected resistive load; measure phase and line voltages and currents; verify that VL = √3 × Vph and IL = Iph.
9	Unit III	Three-Phase Power Measurement – Two-Wattmeter Method	Measure total active power and power factor of a three-phase balanced load using two single-phase wattmeters.
10	Unit IV	Single-Phase Transformer – Turns Ratio and Load Test	Measure primary and secondary voltages to verify turns ratio; perform a load test at multiple loads; compute efficiency
11	Unit V	DC Motor – Speed Variation and Direction Reversal	Connect a DC shunt motor; observe speed change with armature voltage variation using a variable DC supply; reverse terminals to reverse direction.
12	Unit V	Three phase induction Motor –Direction Reversal	Connect a three phase induction motor; interchange supply terminals to reverse direction.
13	Unit V	Solar PV Module – Open Circuit Voltage, Short Circuit Current, and I-V Curve	Measure Voc and Isc of a solar PV module; connect a rheostat load and plot the I-V and P-V curves;

Theory Unit

Equipment / Instruments Required

DC regulated variable power supply (0–30V) and digital multimeters
Resistor kit and rheostat
Single-phase variac, AC voltmeter, ammeter, and wattmeter
Choke coil (inductive load) and capacitor bank for PF correction
CRO / Digital oscilloscope (even a basic model is sufficient)
Three-phase supply panel with balanced star resistive load
Two single-phase wattmeters for three-phase power measurement
Single-phase step-down transformer (230V/12V or 230V/24V) with load panel
Small DC motor (permanent magnet or shunt type, 12–24V)
Solar PV module (5–20W), rheostat, multimeters

Teaching-Learning Methodology

Each 2-hour session begins with a 10-minute pre-lab briefing linking the experiment to its theory unit and a real engineering application. Students record aim, circuit diagram, apparatus, procedure, observation table, sample calculations, result, and inference in their lab record book. A 10-minute post-lab discussion relates the experiment to emerging technologies in the stream. Continuous assessment of observation quality and conduct is maintained.
