DEPT. OF I&E ENGG. CET, BPUT By DR, M, C. Tripathy DO’S AND DON’TS IN THE LAB DO’S:1. Students should carry observation notes and records completed in all aspects. 2. Correct specifications of the equipment have to be mentioned in the circuit diagram. 3. Students should be aware of the operation of equipments. 4. Students should take care of the laboratory equipments/ Instruments. 5. After completing the connections, students should get the circuits verified by the Lab Instructor. 6. The readings/waveforms must be shown to the concerned faculty for verification. 7. Students should ensure that all switches are in the OFF position to remove the connections before leaving the laboratory. 8. All patch cords and chairs should be placed properly in their respective positions. 9. The steps for simulation of different tools should be properly known to the students for the software related laboratory. DON’Ts:1. 2. 3. 4. 5. Come late to the Lab. Make or remove the connections with power ON. Switch ON the power supply without verification by the instructor. Switch OFF the machine with load. Leave the lab without the permission of the concerned faculty. PAGE 3 | E X P T - 1 ELECTRICAL &ELECTRONICS MEASUREMENT LAB
DEPT. OF I&E ENGG. CET, BPUT By DR, M, C. Tripathy Experiment No-1 Aim of the Experiment: Measuring an unknown Resistance using Kelvin’s Double Bridge. Objective: To measure very small resistance( 0.1Ω to 1.0 Ω.) Device/Equipments Required: i. ii. iii. iv. Kelvin’s Double Bridge Trainer Kit(VBK-02) Patch Cords Digital Multimeter Unknown Resistances Circuit Diagram: Theory: A Kelvin Bridge is a measuring instrument used to measure unknown electrical resistors below 1 ohm. It is specifically designed to measure resistors that are constructed as four terminal resistors. PAGE 4 | E X P T - 1 ELECTRICAL &ELECTRONICS MEASUREMENT LAB
