Practical Course IV:

Electricity, Magnetism and Electronics

(For Non-Maths Combinations)

Work load: 30 hrs                                                                                          2 hrs/week

Course outcomes (Practicals):

On successful completion of this practical course, the student will be able to;

• measure the current sensitivity and figure of merit of a moving coil
• observe the resonance condition in LCR series and parallel
• learn how a sonometer can be used to determine the frequency of AC-supply.
• observe the variation of magnetic field along the axis of a circular coil carrying current using Stewart and Gee’s
• understand the operation of PN junction diode, Zener diode and a transistor and their V-I
• construct the basic logic gates, half adder and full adder and verify their truth tables. Further, the student will understand how NAND and NOR gates can be used as universal building

Minimum of 6 experiments to be done and recorded:

1. Figure of merit of a moving coil
2. LCR circuit series/parallel resonance, Q
3. Determination of ac-frequency –Sonometer.
4. Verification of Kirchoff’s laws and Maximum Power Transfer
5. Field along the axis of a circular coil carrying current-Stewart & Gee’s
6. PN Junction Diode Characteristics
7. Zener Diode –V-I Characteristics
8. Zener Diode as a voltage regulator
9. Transistor CE Characteristics- Determination of hybrid parameters
10. Logic Gates- OR, AND,NOT and NAND gates. Verification of Truth
11. Verification of De Morgan’s
12. Construction of Half adder and Full adders-Verification of truth tables
